103 Genre Ya Young Adult Genres

Young Adult

Books written for teen readers, about teen lives.

What it is

Young adult fiction, usually shortened to YA, is fiction published for teenagers. The readers it aims at are about twelve to eighteen, and the main characters are close to their age. YA is defined by its audience. Every other genre on this table is defined by what happens in the story, and YA is the only one defined by who reads it. So any kind of story can be YA: fantasy, romance, a thriller, a mystery, or a quiet realistic novel about ordinary life.

Think about what a genre usually promises. A romance promises a love story that ends happily. A mystery promises a solution. Horror promises fear. The YA label promises none of those things on its own. Its promise goes to a reader of a certain age, and it says: this was written with you in mind, about someone going through the years you're going through.

You'll find YA fantasy of every kind, from epic fantasy to fairy-tale retellings. You'll also find YA romantasy, science fiction, thrillers, horror and historical fiction. On top of that, YA holds a huge amount of contemporary realism, stories of everyday teen life that have no genre page of their own on this table. You could argue that realism is the category's heartland.

The genre's rules still apply under the YA label. A YA mystery still has to play fair with its clues. A YA romance still owes the reader the relationship it promised. What YA adds on top of the genre comes from the age of its readers: where the narrator stands, how the voice sounds, which adults stand between the book and the teen who reads it, and how these books get published and found.

The label is partly a business decision, so the same book can be YA in one country and adult in another. Markus Zusak's The Book Thief came out as an adult novel from Picador in Australia in 2005. In 2006, Knopf published it in the United States as a book for young readers. Zusak's novel also turns up on the Show, Don't Tell page.

The usual shorthand for YA has three parts: a teenage main character, a close and immediate voice, and a coming-of-age plot. Each one is a custom. A YA book can break any of them and still be YA.

For a working writer, the most useful line to learn is the one between a YA novel and an adult novel that happens to have a teenager in it. The character's age doesn't decide it. Often the content doesn't either. What decides it is where the narrator stands. A YA book is told from inside the teen years. The stakes are the size they feel to a sixteen-year-old, and no adult is smiling back at it all from later in life. Stay inside adolescence and you're writing YA. Rise above it, with a narrator who already knows how things turned out, and you've written an adult book.

Cheryl Klein, a children's and YA editor, put this into a single sentence on her blog, Brooklyn Arden, on June 5, 2009. In her definition, a YA novel centers on its teenage protagonist's experience and growth, and the teen's own choices and actions drive the story. The narration stays "with relative immediacy to that teenage perspective" all the way through. She was clear that first person isn't required. What her definition rules out is an adult looking back on the teen years from a distance. She put YA protagonists at fourteen to eighteen.

Kate Angelella, an editor, draws the same line in her guide to writing YA on the Reedsy blog, last revised in October 2025. For her, the split between YA and adult comes down to the narrator's vantage point, and the character's age doesn't settle it. Her two counterexamples are Curtis Sittenfeld's Prep (2005) and Jeffrey Eugenides's The Virgin Suicides (1993). Both novels are about teenagers. Both are told through an adult's memory, and both were published and shelved as adult fiction.

Vantage changes the size of everything. An adult remembering a humiliation in the school lunchroom turns it into a story about something that mattered once. A fifteen-year-old telling it as it happens feels a catastrophe. A YA book has to put it on the page as a catastrophe.

A narrator looking back can be wise, ironic and kind. A YA narrator has no way to know how things turn out, and the reader is kept just as much in the dark. The urgency readers feel in YA comes straight from that missing hindsight. Nobody bolts it on as a style.

Past tense is fine in YA. So is a narrator telling the story soon after it happened, the way The Outsiders does. What YA rules out is the adult frame: a grown-up speaker who has matured, settled down and made sense of it all.

Vantage sits underneath other choices, such as first person and present tense. YA leans toward both, and the pages on those two elements weigh the trade-offs. Vantage is the one thing YA insists on. Building the voice itself is a job for narrative voice.

No law sets the age of YA readers or YA heroes. There are only customs, and the groups that state them don't agree. Learn them before you put a label on your own book.

Librarians set one range. The Young Adult Library Services Association (YALSA) is a division of the American Library Association (ALA). For its Printz Award, YALSA defines YA readers as ages 12 through 18. A book qualifies if its publisher calls it YA, or if it was published for that age range. Either one is enough.

Market researchers set another. A 2012 study by Bowker Market Research counted books that publishers had classed for ages 12 to 17.

Bestseller lists set a third. In December 2012, The New York Times replaced its single children's chapter-book list with separate middle-grade and YA lists. Its YA list covers ages 12 to 18.

Editors have their own guidelines. In The Magic Words (W. W. Norton, 2016), listed below, Klein separates middle grade from YA on five measures: the main character's physical age, emotional age, content, subject, and prose. On age, she notes that readers read up. They like characters their own age or older, and never younger. Klein gives the booksellers' standard: a main character aged twelve or under means middle grade, and thirteen or over means YA. ALA's award guidelines differ slightly. A main character past eighteen, or in college, usually signals adult fiction. That gives Klein a YA band of 13 to 18.

For the emotional difference, Klein passes on a line from the novelist Laura Ruby: "Middle grade is about ability; YA is about identity."

On length, Klein borrows the ranges of the literary agent Jennifer Laughran. Realistic YA runs 35,000 to 75,000 words. Fantasy runs 50,000 to 150,000. A manuscript over 100,000 words gets a hard look from editors and agents. Klein offers these as working norms of 2016, and she doesn't present them as rules. Lengths drift.

One publisher shows how the age split works in practice. At the time of writing (checked October 3, 2026), Entangled Publishing divides its YA romance list by age into two imprints. Mischief Books wants main characters aged 13 to 18, for readers 13 and up, at 80,000 to 100,000 words. Mayhem Books publishes what it calls "older YA" for readers 16 and up, with main characters aged 16 to 19, at 90,000 to 120,000 words, and it takes darker themes. Both imprints cap contemporary romance at 90,000 words. These are one house's editorial specs, and they can change. Read the live pages before you submit anything.

Put together, a few customs come out of all this. Most YA main characters are 15 to 18, and Klein's 2009 definition said 14 to 18. Readers read up, so a fourteen-year-old reader will happily follow a seventeen-year-old lead but not a twelve-year-old one. Younger YA and upper or older YA are more and more often treated as separate shelves, and upper YA drifts toward adult content. A main character who is in college or holding down a job has left the category and sits on the new adult shelf.

There are two usual candidates for the first YA novel, and which one wins depends on what you count.

The usual starting point is Maureen Daly's Seventeenth Summer (Dodd, Mead, 1942). Seventeen-year-old Angie Morrow tells it in first person. It covers a single summer in Fond du Lac, Wisconsin, and her first serious romance, in a gentle and safe world. The book marks the start of the modern era because its author was young herself, teenagers read it avidly, and it showed publishers that a teen market existed. Michael Cart, a past president of YALSA, opens his history of the category, Young Adult Literature: From Romance to Realism (listed below), with Daly's novel. His first chapter is titled "From Sue Barton to the Sixties" and starts with what came before: the career novels of the 1930s and other vocational and series fiction for older teenagers of both sexes. Helen Dore Boylston's Sue Barton, Student Nurse (1936) is the one that gave the chapter its name.

The other candidate is S. E. Hinton's The Outsiders (Viking, 1967). The case for it rests on candor. Daly's novel is mild, and its world is secure. Hinton wrote about gang violence, deaths, and three brothers with no parents keeping a home together, and she was a teenager writing about teenagers she knew. On this view, 1967 is the year YA stopped showing adults' wishes about teenage life. Librarians had already organized around this age group in 1957, as the history of YALSA further down shows.

You don't need to settle the argument. What it shows you is the two forces that have always defined the category: the reader it's written for, and a running fight over how frank it's allowed to be.

In the 1970s, Hinton's candor turned into a trend. Its label was the problem novel: one hard issue per book, such as drugs, divorce or pregnancy, with the plot built around a teenager facing it. Robert Cormier's The Chocolate War (Pantheon, 1974) became the benchmark of those years for its bleak ending. A boy refuses to take part in his school's chocolate sale, and a secret society, helped by the acting headmaster, breaks him. Judy Blume's Forever (1975) showed a first sexual relationship frankly. Both books were still being fought over on ALA's list of the hundred most challenged books of 2000 to 2009, where The Chocolate War ranked third and Forever sixteenth.

Around the turn of the century, the Harry Potter novels came out as children's books and were read by people of every age. In July 2000, The New York Times created a separate children's bestseller list, largely because of them. The Dramatic Question page looks at those books. In January 2000, the first Printz Award was presented.

Stephenie Meyer's Twilight (Little, Brown, 2005) proved that YA romance could sell like an adult blockbuster and pull in a large adult audience. The Heroine's Journey page works through it. Then Suzanne Collins's The Hunger Games (Scholastic, 2008) set off a dystopian wave that ran until 2013. The Dystopian page tells the whole history of that wave.

The 2010s added two things. The first was a long argument, started by authors and readers, about whose stories YA had been telling. As a result, YA lists took on many more LGBTQ+ authors and authors of color. The second was new adult.

New adult grew out of a 2009 contest at St. Martin's Press, run by the editor Dan Weiss with his assistant, S. Jae-Jones. The contest called for "new adult" fiction: books like YA that could be published as adult, with characters roughly 18 to 26, grown up but without a settled adult life. The label took hold in 2012 and 2013, mostly through self-published college romances such as Colleen Hoover's Slammed and Jamie McGuire's Beautiful Disaster, which major publishers then bought. Today new adult is a shelf of its own, mostly romance. New adult is more than older YA. If your main character is in college, the book probably belongs there.

For most plot questions, go to the genre itself. What the readers' age does to those plots shows up on several genre pages. The Romance page notes that a happy-for-now ending often suits YA romance, because a promise of forever from two seventeen-year-olds can ring false. The Paranormal page deals with the age gap between an immortal and a teenager, which YA paranormal has to treat as a problem and never as something to savor. The Dystopian page shows how the wave made the trilogy standard. The Pen Name page takes up whether a YA author should publish adult books under the same name.

Coming of age has no fixed structure, but it does have a usual arc. The main character starts out defined by other people, by family, school and friends, and ends having chosen a self. On the Character Arc page, that counts as a positive arc. Laura Ruby's line about identity sums it up. YA also often works through want vs need. The gap between what a teenager chases and what she needs is what those years are made of.

For structure, YA borrows from its genre. Jessica Brody fitted Save the Cat to YA in Save the Cat! Writes a Young Adult Novel (2023), and the Save the Cat page's own worked example, Angie Thomas's The Hate U Give (2017), is a YA novel. The Hero's Journey suits fantasy and adventure. The Heroine's Journey fits books led by romance, as Twilight shows. Three-act structure covers most contemporary novels. The school year is a structure too. It hands you acts, deadlines and set pieces, and many contemporary YA novels use it, Speak among them.

A YA book also makes its reader promise on two levels at once: one about its genre, and one about the age of its readers.

Why it matters

A YA book gets judged three times over. YA is one of the biggest and most visible parts of publishing. Its professional gatekeepers are more organized than those of any other category on this table, and many of its readers are adults. So a YA book is judged by the teenager it was written for, by the adults who stand between that teenager and the book, and by adults reading it for themselves. The route to teen readers runs through adults, and plenty of adults read YA too. Both facts shape how a YA book gets written and how it gets judged.

A teenage reader trusts you with five things, and the first is a narrator nobody is steering. Readers can sense an adult behind the narrator pulling strings. One giveaway is a closing moral that matches the lesson a parent would want taught. Another is slang lifted from the last internet cycle. That slang dates the book and loses the reader on the spot.

The second is feelings at their real size. First love, a friend's betrayal and a parent's failure weigh what they weigh at sixteen. A narrator who hints that all of it will shrink later has stepped outside the category.

The third is a main character who acts. Teenagers live under adult authority. If capable adults were on hand, they would settle most plots. YA has two standard answers. The adults can be absent, distracted or part of the problem. Or the main character can have a reason, valid in her world, to act where the adults won't. Either way, the young character makes the decisions at the turning points. The Agency page covers the craft, and it pays off more in YA than in any other genre.

The fourth is the truth about hard things. Teen readers accept very dark subjects, and the most admired YA books often go there. What readers resent is darkness used for effect, or darkness sanded down in the last chapter when the author loses nerve.

The fifth is hope, usually, with no guarantee. In her 2009 definition, Klein noted that YA tends to end with some hope, a sense that the main character can face what comes next. Then she questioned whether hope should be required, and pointed to The Chocolate War as proof that it isn't. The category mostly leans toward a door left open at the end. Treat that as a tendency and nothing more.

YA readers tell you exactly where they stopped believing. Their complaints come back again and again. "The parents were idiots" means the grown-ups were written as fools so the plot could happen. "Nobody talks like that" means the voice was an impression. "Preachy" means the book was built around its message. "Insta-love" means the romance was announced and never earned, which is the chemistry problem in YA form. "Thirty-year-olds in school uniform" means the teenagers had an adult's confidence, judgment and resources, with none of the limits of being seventeen.

A newer complaint is about the shelf itself. More and more readers say "this should have been shelved as adult" about a book. They mean the content belonged to an older reader, and the buyer felt misled. YA is the only genre on this table where readers watch the shelf. Teenagers and the adults around them know the label implies the book is suitable, and they notice when a book strains against it.

The shelf stretches a long way on form. Verse novels are well established. Jason Reynolds's Long Way Down (Atheneum, 2017) takes place during one elevator ride lasting sixty seconds, as a fifteen-year-old sets out to avenge his brother. It earned three honors, from the Newbery, the Printz and the Coretta Scott King awards. Elizabeth Acevedo's The Poet X (2018) follows a fifteen-year-old who finds her way out of her family's silences by writing. It won the National Book Award for Young People's Literature and the Printz. Comics are established too. Alice Oseman's Heartstopper began as a webcomic on Tumblr and Tapas in 2016, went to print through crowdfunding, moved to Hachette Children's Group in 2019, and became a Netflix series in April 2022. YA also welcomes documents, case files, several narrators, unreliable narrators and narrators who are dead.

Two things stay fixed whatever the form. Those two are vantage and agency. Form, genre and darkness are free, up to whatever the shelf you're aiming at will hold. Teenagers have to drive the book, and it has to be lived from inside adolescence. Content is a third limit, and it gets negotiated rather than fixed.

No other genre on this table has so many adults standing in between. A school librarian buys the book. A teacher assigns it. A public librarian puts it on display. A parent pays for it. A trade journal for librarians gives it a star. These adults make up much of the market and nearly every institution around it. Three consequences follow for you as a writer.

First, the school and library channel brings money and reach. Traditionally published YA gets reviewed in the journals librarians and booksellers read. It gets bought for school and public collections, put on state and national reading lists, and assigned in class. A book that gets assigned can stay in print for decades, as The Outsiders shows. Self-published YA has a hard time getting into this channel, because its reviewing and buying routes are built around publishers.

Second, people who won't read the book judge its content. Age ranges are printed on jackets and in catalogs, and content notes are common. Librarians shelve by range, and many school libraries split their holdings by grade. A darker book can reach the older teen who goes looking for it that way. The cost is that language, sex and violence get weighed by adults acting on behalf of other families' children. Write the book you mean to write, then ask your publisher where it plans to place it.

Third, some adults will object. Objections are nothing new in YA. Right now they are part of a national fight.

Teen books have long ranked high on the most-challenged lists. What follows is the state of play as of October 3, 2026. ALA's Office for Intellectual Freedom collects reports of attempts to remove or restrict books in public, school and academic libraries, and each April it publishes a most-challenged list. On its hundred most challenged books of 2000 to 2009, The Chocolate War was third and Forever sixteenth. Laurie Halse Anderson's Speak made that list and the one for 2010 to 2019.

The latest list is mostly teen books. ALA's list for 2025, released April 20, 2026, was led by Patricia McCormick's Sold, Stephen Chbosky's The Perks of Being a Wallflower and Maia Kobabe's Gender Queer. Books by Sarah J. Maas, Ellen Hopkins, Malinda Lo and John Green were on it too. ALA's list named eleven titles in all, and most of them were first published for teenagers.

PEN America counts something different. PEN America, a writers' organization, tallies books removed or restricted in US public schools each school year. Its report The Normalization of Book Banning (October 2025) counted 6,870 cases across 23 states in the 2024 to 2025 school year. ALA and PEN America count different things by different methods, so their totals can't be compared directly.

The Department of Education rejects the word "ban" for any of this. On January 24, 2025, the United States Department of Education's Office for Civil Rights dismissed complaints about book removals. The Department described the removals as protecting students from sexually explicit, age-inappropriate material. It called the previous administration's approach a "book ban hoax" and set it aside. In the Department's view, a book pulled from a school collection can still be bought, borrowed somewhere else, and read at home. Parents and elected school boards, it holds, have the right to decide what suits their pupils.

Plan your book without picking a side. Nothing here takes a side, and your planning shouldn't either. Recent reports from both ALA and PEN America name the same three kinds of book as the most targeted: books with sexual content, books that portray sexual violence, and books centered on LGBTQ+ characters or on people of color. Most of the fight happens in school libraries. Your publisher's school and library team knows how the current climate bears on your particular book. So write truthfully, make sure the content serves the story, and then ask the sales staff what conditions look like now. Laws and policies vary by state and by year, so check the current position yourself.

How YA gets published and read changes fast, so check the date. The next few paragraphs describe how the trade works, as checked on October 3, 2026. Publishing moves quickly, and YA moves faster. Check current conditions before you act on any of it.

Many YA buyers are adults. A 2012 study by Bowker Market Research, Understanding the Children's Book Consumer in the Digital Age, was reported in Publishers Weekly on September 13, 2012. It found that 55 percent of buyers of books for ages 12 to 17 were 18 or older. The biggest group of buyers was aged 30 to 44. Adult buyers said they were buying for their own reading 78 percent of the time. Keep the limits in mind. Bowker counted buyers, and readers are a different count. The figures are a 2012 snapshot from the height of the Hunger Games years, and they aren't current. The lesson still holds: a category aimed at teens is bought largely by adults, and that pulls some books upward in age. Look for a newer survey before you cite any share.

Discovery is social. BookTok, on TikTok, has reshaped YA more visibly than most categories. In September 2021, Publishers Weekly reported that backlist YA titles were back on bestseller lists years after they first came out, because readers were filming their reactions. E. Lockhart's We Were Liars (2014) and Adam Silvera's They Both Die at the End (2017) were among them. A good cry had become close to a requirement for a recommendation.

Authors are split on BookTok. In October 2022, Publishers Weekly asked YA authors whether BookTok was a boon or a burden. Several called it transformative. Others described pressure to perform on camera, which cost them writing time. Both can be true at once. What tends to help on the platform is a recognizable trope, a strong emotional premise, and a cover that works on a phone. Platforms change faster than anything else described here.

Format follows the buyers. Major houses have generally launched YA in hardcover, with the paperback about a year later, though some lists try paperback first. The hardcover serves the library and school trade, which buys sturdy editions. The paperback catches teenagers spending their own money. Self-published YA goes straight to ebook and paperback, and it leans hard on social discovery and series momentum.

YA series have a ceiling. Contemporary realism is mostly standalone books. Fantasy, science fiction and dystopian YA are commonly trilogies and duologies. Mystery has built its own series pattern, as Holly Jackson's books show below. The ceiling comes from the readers, who grow older. A seventeen-year-old can't plausibly carry twelve books, while an adult detective of forty-five can run that long. The Series and Series Arc pages cover the trilogy and duology patterns.

For market size, go to the people who measure it. Circana BookScan, called NPD BookScan until 2023, records US print sales at the register. Publishers Weekly reports figures through the year and in its annual roundups, and its children's coverage includes YA. Nielsen BookData does similar work outside the United States. You won't find a current sales figure here, on purpose. Any number would be out of date within the year.

The institutions around YA are unusually mature, and librarians run most of them. On June 24, 1957, the ALA created the Young Adult Services Division when the Association of Young People's Librarians split in two, one division for children and one for young adults. In 1992 the division took its current name, the Young Adult Library Services Association. YALSA puts out booklists every year and gives several awards. Its members are professional readers, and their opinions steer what schools and libraries buy.

The Printz Award is YA's prize for literary excellence. YALSA gives the Michael L. Printz Award, named for a school librarian at Topeka West High School in Kansas and sponsored by the magazine Booklist. It was approved in January 1999 and first presented in January 2000, to Walter Dean Myers's Monster. The judges are told outright that popularity and message are not criteria. At the time of writing, the latest winner, announced January 26, 2026, is Legendary Frybread Drive-In: Intertribal Stories, edited by Cynthia Leitich Smith.

Two more awards show how easily books cross between shelves. The Margaret A. Edwards Award honors one author's lasting contribution to YA readers. It was first given in 1988, under a previous name, and its first winner was S. E. Hinton. The Alex Awards began in 1998 and became an official ALA award in 2002. Each year they pick ten books published for adults that have special appeal to readers aged 12 to 18. Between them, these two awards show books moving easily between the adult and YA shelves.

The National Book Award has a category for young readers. The National Book Foundation ran children's categories from 1969 to 1983. Its Young People's Literature category began in 1996, and the first winner was Victor Martinez's Parrot in the Oven. The category covers middle grade as well as YA, and YA novels often win it.

Real-world examples

The Outsiders (1967): a story written up for English class

Viking published S. E. Hinton's The Outsiders on April 24, 1967. Hinton started it at fifteen and wrote most of it at sixteen. She drew on the feud between the greasers and the Socs at her school in Tulsa, Oklahoma. The greasers are the working-class kids, and the Socs are the well-off ones. Hinton was eighteen when the book came out.

The narrator is Ponyboy Curtis, who is fourteen. His parents are dead, and his two older brothers are raising him, one of them working to hold the three together. A fight goes wrong. Ponyboy's friend Johnny kills a Soc to save Ponyboy, and the two of them run. A church fire follows, then a gang fight, and two deaths. The novel has been around since 1967 and is a classroom staple, so its ending is widely known and openly discussed.

The lesson about vantage comes in the last chapter. Ponyboy is failing English, and his teacher offers him a pass if he writes a good theme. He writes up everything that happened, beginning with the sentence that opens the novel. So the whole book is a school assignment by a fourteen-year-old, written soon after the events by the boy who lived them. The telling is in past tense, but it stays entirely inside adolescence. No wiser older self appears anywhere on the page. Ponyboy is still grieving as he writes.

Hinton defended that vantage herself. The New York Times Book Review printed her essay "Teen-Agers Are for Real" on August 27, 1967, and she was nineteen when she wrote it. She argued that teen fiction was all dates with football heroes. Adult authors, she said, wrote what they wished teen life was like and ignored what teenagers really dealt with, from school politics to gangs. Her essay stands as the category's founding statement about telling the truth.

The book teaches three lessons. First, the frame of a YA novel can be the teenager's own act of telling. That solves the problem of the narrator looking back: the story gets told, but never from adulthood.

Second, the adults in YA are often absent or useless for reasons inside the story world, and never just for the plot's convenience. Here the parents are dead, the brothers are barely grown, and the police are mostly a threat.

Third, the gatekeepers. The Outsiders has been assigned in classrooms for decades and challenged for just as long. It ranked 38th on ALA's list of the most challenged books of the 1990s, for violence, smoking, drinking and family dysfunction. Both facts come from the same place: adults choosing what teenagers read, and disagreeing about it. In 1988, Hinton received the first Margaret A. Edwards Award.

Speak (1999): a voice that will not say the thing

Farrar, Straus and Giroux published Laurie Halse Anderson's Speak on October 22, 1999. That year it was a National Book Award finalist in the young people's category. In the Printz's opening year, it was named a Printz Honor book.

Melinda Sordino starts high school as an outcast. At a party at the end of the summer, she called the police, and nobody knows why. The reason comes out slowly. An older student raped her at that party.

Anderson tells it in present tense and first person, starting on Melinda's first morning of high school, and the narration never leaves that point. Here the vantage is at its hardest. An adult looking back on a rape at fourteen might say it on page one and spend the rest of the book on what it meant. Melinda can't say it, even to herself, and the shape of the book matches that.

Instead of chapters, the book follows the four marking periods of the school year. The sections are short and broken up, with lists and report cards among them, and Melinda's grades slide as the year goes on. The reader learns what happened at about the speed Melinda finds the words for it. The title is the arc: Melinda finds her voice.

Three lessons come out of it. First, the marking periods hand Anderson her acts, her deadlines and the passing of time, and the device couldn't be more ordinary. Second, Melinda withholds fairly. She is hiding the fact from herself, and she isn't hiding it from the reader to set up a twist. Readers can feel the difference.

Third, Speak is the clearest case of the gatekeepers at work. Schools teach it widely as a story about consent and recovery, and it has been challenged again and again. It ranked 60th on ALA's list for 2000 to 2009 and 25th on the list for 2010 to 2019. A story about a girl who was silenced has often drawn requests to remove it.

The book has had a long afterlife: a 2004 film with Kristen Stewart, and a 2018 graphic novel with art by Emily Carroll that brought it new readers.

Six of Crows (2015): a heist crew and no adults coming to help

Henry Holt published Leigh Bardugo's Six of Crows on September 29, 2015. The book is set in her Grishaverse, in Ketterdam, a trading port loosely modeled on Amsterdam in the Dutch Golden Age. A crew of six young criminals is hired to break a scientist out of the most secure prison in the world.

Bardugo fixed their ages on purpose. Kaz Brekker, who plans the job, is seventeen. Inej Ghafa, his spy, is sixteen. The other four are sixteen to eighteen. The book is told in third person, and five of the six take turns as the viewpoint character.

The book earns its place here by breaking two supposed YA rules, first person and present tense, while keeping the two that matter. In form, it's a heist fantasy with several third-person viewpoints, the kind of multi-POV book readers know from adult fantasy. Adults read it in huge numbers too, especially after Netflix folded its characters into the Shadow and Bone series in 2021.

What it keeps is vantage and agency. Every viewpoint belongs to a teenager and stays close and immediate. The crew's wounds from the past are fresh, raw and unresolved, and nobody recalls them from a safe distance.

The adults are the problem. The merchant who hires the crew means to cheat them. The gang boss who wrecked Kaz's childhood is his enemy. Officials are obstacles. No capable, kindly grown-up stands anywhere near the job, and the story depends on that. With nobody coming to rescue them, the teenagers have to be good enough. Bardugo keeps her young characters in control by building a world that forced them to grow up early, and that early adulthood is also the emotional subject of the book.

Spoiler: the heist succeeds, the client refuses to pay, and he holds one of the crew captive. The ending leads straight into the sequel, Crooked Kingdom (2016). Duologies and trilogies are standard in YA fantasy, and Six of Crows is a model first volume. It closes its own plot and opens the next one.

A Good Girl's Guide to Murder (2019): a school project as a license to investigate

Holly Jackson's debut came out from Electric Monkey in the United Kingdom on May 2, 2019, and from Delacorte Press in the United States on February 4, 2020. Pippa Fitz-Amobi, called Pip, is seventeen. For her school research project, she picks a case her town thinks is closed. Five years earlier, Andie Bell disappeared. Her boyfriend, Sal Singh, was blamed, and he then took his own life. Pip doesn't believe that version.

The book won Children's Fiction Book of the Year at the British Book Awards in 2020. It grew into a trilogy plus a prequel novella. In 2024 it was adapted for BBC Three, and Netflix carries it in most other territories.

The book solves the central craft problem of the YA mystery. An amateur sleuth always has to explain why she, of all people, is the one asking questions. For a teenager, the answer has to stand up to parents, teachers and police. A school assignment does. It also brings a deadline, a supervisor and a reason to write everything down. The Cozy Mystery page has more on the amateur sleuth's motive.

Jackson explained where the idea came from in an essay for Writing.ie on June 10, 2019. She had watched her younger sister do an Extended Project Qualification, an independent research project taken in the last years of school in England. That project is what made a seventeen-year-old's investigation of an old murder believable.

Pip's typed production logs run through the story: transcripts of interviews, posts from social media, a map with notes on it, and a spider diagram of suspects. The reader sees the evidence as if looking straight at the raw case file. In the last third, the logs shrink as the danger grows, and scenes take over from documents. Jackson plotted the whole book before she wrote a sentence, because the double structure couldn't be improvised. She drafted it in about eleven weeks.

The solution stays unspoiled here. The book is a twisty mystery, and the solution is the payoff.

The lesson: a teenage lead in a genre built for adults needs a reason, rooted in her own life, for doing adult work. The reason is strongest when it also shapes the book's form. In Jackson's book, the school project is the premise, the license to investigate, the structure and the clock.

An everyday scenario: Soft Serve and the narrator who already knew

Imagine a novelist named Shona Petrie. She has two adult novels out, both well reviewed, and she is drafting a third about a summer that has stayed with her. In Soft Serve, sixteen-year-old Jodie Marwood takes over her father's ice-cream van route in June, after he has a stroke. Over the summer she keeps the business going, falls for the boy who runs the rival van, and finds out the debts are bigger than she was told. Shona's agent thinks the book could be YA, so Shona sends it out. The YA editors who read it all decline on the same grounds: lovely, wrong shelf.

For her first check, Shona writes a vantage line for each chapter. Each line is one sentence saying who narrates, how old the narrator is while narrating, and what the narrator knows that her younger self didn't. Chapter one comes out as Jodie, about forty, knowing her father dies the following spring and the van is sold. Every chapter after it reads the same. The narrator is warm, funny and forgiving, and she keeps explaining what things meant: I didn't understand then that he was frightened. Years later I would realize. Every one of those sentences is lovely, and every one pushes the book toward the adult shelf.

Shona has two honest options, and each has a price. She can keep the adult frame and publish the book as adult fiction about a teenage summer, where the hindsight becomes a strength. Or she can rewrite it from inside the summer: Jodie at sixteen, living it, not knowing her father will die, unsure whether the boy means it, and handling the debts in ways an adult wouldn't.

She chooses the rewrite, and it takes more than cutting the adult sentences. Every scene has to be redone, because a narrator the reader knows will survive can no longer reassure anyone. The debts turn into plot instead of memory. The boy with the rival van turns into an antagonist. Jodie's mistakes turn into decisions whose outcomes she can't see.

Then Shona runs a second check, a gatekeeper pass. She rereads the new draft as the school librarian deciding where to shelve it. The swearing is in character, so it stays. The party scene where Jodie drinks stays too, because it carries consequences. One paragraph of explicit sexual detail from the adult draft goes. Sex is allowed in YA, but this book is aimed at the younger readers, and the scene works fine implied. She makes the call on purpose and tells her editor why.

The point of the scenario: hindsight in the narration is what separates the adult shelf from the YA shelf. The same story can fit either one, at a different price. Vantage and content are both choices, and you make them on purpose.

Try it yourself

Work from your draft or your outline. Each step looks at one part of what makes a book YA.

  1. Write the vantage line. Write one sentence naming who tells the story, how old the teller is while telling it, and how long after the events. If the answer is an adult looking back, or a teenager who already knows how it ends, you have adult fiction with a teenage lead. That might be an excellent book, but it's a different kind of book.
  2. Sweep for hindsight. Search the whole draft for later, years, I would learn, I didn't know then, looking back and now I understand. Each one marks a spot where the narrator steps out of adolescence. Cut it, or turn the knowledge into something the character discovers on the page.
  3. Pick the reader and the shelf. Choose younger YA, upper YA or new adult. Write down your main character's age, the youngest reader you imagine, and two recent books that sit together on that same shelf. Check the publishers' pages or library catalog entries to see what age range they give for those books.
  4. Audit the adults. List every adult character and what each one would do if they knew everything your main character knows. Anyone who would settle the plot needs a reason inside the story for not acting, and it has to be a reason a teenage reader will accept.
  5. Find out who decides. Mark every turning point in your outline and name who makes each decision. Wherever an adult, a coincidence or the needs of the plot decides, give the decision back to your main character. The Agency page has the full method.
  6. Fix the dialogue. Read it aloud and strip out the slang. Then put back only what fits this character and this place. Teen speech on the page runs on rhythm, dodging and what goes unsaid, much more than on current vocabulary. The Character Voice and Subtext pages show how.
  7. Run the gatekeeper pass. Reread the draft as a school librarian deciding where to shelve it. Then reread it as a parent glancing over a fourteen-year-old's shoulder. You aren't hunting for cuts. You're checking that every hard scene earns its place, so you can defend it to an editor, a librarian or a reviewer.
  8. Write the last page twice. Write one version with the door open and one with the door shut, and compare them. The category leans toward the open door. If you choose the shut one, choose it on purpose, the way Cormier did.
  9. Draft the blurb in a teenager's words. Write the blurb the way a teenager would describe the book. Then test it: would a sixteen-year-old say these words to a friend? The Blurb page covers the craft.

Common mistakes and misunderstandings

Calling a book YA because the lead is sixteen. A sixteen-year-old main character is necessary, but it's far from enough. Vantage decides. Editors turn down beautifully written, memoir-style adult novels about a teenage summer for reasons that have nothing to do with quality.

Writing a narrator who is secretly forty. On the surface the narrator is a teenager in present tense, but the thinking, judging and forgiving all belong to an adult. Present tense won't create immediacy when the mind behind it has already finished processing everything.

Making adults useless to serve the plot. Readers catch it at once. Absent adults are fine, and so are adults who get in the way. Adults who turn foolish exactly when the plot needs them to are a problem. Put the reason for their failure inside the world.

Preaching instead of telling a story. A YA book with a moral bolted on gets spotted fast, and it is the oldest failure in the category. Theme lives in what the characters choose, and never in a speech at the end. The Theme page goes further.

Using last year's slang. Slang dates a book before it's even published. Voice comes from how the character sees the world, and up-to-date vocabulary adds little to it.

Treating YA as a genre. YA is a readership, so YA fantasy has to satisfy fantasy readers as well as teenage ones. Writers who know the age group well often underrate what the underlying genre demands. Read the page for your genre too.

Assuming YA has to be mild. Some of the most praised books in the category deal with rape, murder, addiction and grief. The only limit is honest treatment from inside the main character's experience.

Assuming anything goes. Here is the opposite mistake. Gatekeepers negotiate content. An upper-YA book with the sexual content of an adult romance will be shelved, reviewed and sometimes challenged on that basis. Decide on purpose which shelf your book belongs on.

Writing for the adult buyers. Many YA buyers are adults, and that tempts writers to aim older. Write for the teenager. Aiming older loses the teen reader and gives the adults nothing new.

Treating the latest boom as a plan. YA trends are big and short. By the time a shelf looks crowded, the buying has usually stopped. The Dystopian page tells this story best, with dates.
