The best YA mystery books all start the same way: an adult says the case is closed, and a seventeen-year-old doesn't buy it. If you want one title tonight, read A Good Girl's Guide to Murder. If you've already read it, keep going, because the other seven are sorted by the thing that makes teen detective fiction work: why the adults are useless.
Adult mysteries hand the case to someone with a badge or a license. YA can't, so every book has to explain why a kid with homework is doing the police's job. Some writers say the police already closed the file. Some make the teen a suspect. The darker ones make the adults part of the secret. That answer tells you more about the book's tone than the cover does, so it's how this list is organized.
🗂️The case is closed
The police have an answer, and the whole town has accepted it. Your detective is the only person still asking questions. These are the most fun of the four groups: fair-play clues, and a sleuth you can root for.
- Adults: case closed five years ago
A Good Girl's Guide to Murder
Holly Jackson · 2019Pip Fitz-Amobi picks a senior capstone project that nobody wants her to do: re-examine the murder of Andie Bell, which the town blamed on Andie's boyfriend Sal Singh. The book mixes chapters of prose with Pip's project logs, interview transcripts and maps, so you can play along with her evidence. It gets darker than the pastel cover suggests, with drugs, a threatened dog, and a killer who notices her.
Verdict: the easiest recommendation on this page. Three books plus a novella, and the first one is fine as a standalone.
- Adults: case cold since 1936
Truly Devious
Maureen Johnson · 2018Stevie Bell wins a place at Ellingham Academy, a free school in the Vermont mountains, and goes there mainly to solve its 1936 kidnapping of the founder's wife and daughter. The chapters alternate between Stevie's present and archive material from the thirties. A new death on campus happens halfway through.
Verdict: slower and funnier than Jackson, and it does not wrap up in book one. Budget for the whole trilogy.
🚨You're the suspect
In this group the adults are investigating, but they're investigating you. The teen solves it to clear their own name.
- Adults: think one of the kids did it
One of Us Is Lying
Karen M. McManus · 2017Five students walk into detention, and only four walk out: Simon, who runs the school gossip app, dies of an allergic reaction in the room. The brain, the athlete, the princess and the criminal each narrate in turn, and each has a secret Simon was about to post. It borrows from The Breakfast Club on purpose.
Verdict: the fastest read here. Short chapters, four narrators, and the reveal is about secrets more than clues. That's great for a binge but a letdown if you wanted fair-play clues.
🔒The adults are the secret
Nobody's hunting a killer. The mystery is the family itself: rich people, a private island or a dead billionaire, and something every adult agreed not to talk about.
- Adults: the family closed ranks
We Were Liars
E. Lockhart · 2014Cadence Sinclair spends every summer on her grandfather's private island off Massachusetts. After an accident in her fifteenth summer she can't remember what happened, and her family won't tell her. Lockhart's prose is spare and strange, with fairy-tale interludes about a king and his three daughters.
Verdict: 240-odd pages, readable in one sitting, and the twist is the book. Don't look anything up first. Readers either love the ending or feel cheated by it.
- Adults: the dead man set the game
The Inheritance Games
Jennifer Lynn Barnes · 2020Avery Grambs is broke and living in her car when a billionaire she has never met leaves her almost all of his fortune. The catch is that she has to live in his mansion with the family he disinherited, including four grandsons raised on his riddles. The clues are puzzles hidden in the house, like secret passages, codes in books and a will with layers.
Verdict: the most escapist pick. The love triangle gets as much page time as the puzzle, which you may love or hate.
- Adults: every one of them is playing
The Westing Game
Ellen Raskin · 1978Sixteen heirs of the millionaire Sam Westing are paired up and handed clue words, and whoever works out who "took his life" gets the fortune. Turtle Wexler, thirteen, who kicks people in the shins, is the sharpest player. It won the 1979 Newbery Medal and reads a bit younger than everything else here.
Verdict: the gateway pick for a twelve-year-old, or for an adult who never read it. The clues are planted for you, and they are fair.
🕯️The adults already failed
These are the heavy ones. The system let someone down before page one, and the teen investigates because nobody else will. Check the content notes before you hand either of these to a younger reader.
- Adults: stopped looking
Sadie
Courtney Summers · 2018Nineteen-year-old Sadie goes after the man she believes killed her little sister, Mattie. Her chapters alternate with transcripts of a true-crime podcast whose host is trying to find Sadie herself. So you're reading the case and the coverage of the case at once. There's an audiobook with a full cast, and it's worth hearing.
Verdict: the best book on this list and the hardest to recommend. Child sexual abuse is central to it, though off the page, and the ending doesn't give you the answer you want.
- Adults: using her as an informant
Firekeeper's Daughter
Angeline Boulley · 2021Daunis Fontaine is eighteen, Ojibwe and white, and she has just put college on hold. After she sees a murder, she agrees to help a federal investigation into a new drug in her community around Sault Ste. Marie. The mystery is who is cooking it. The real question is what the feds will do with what she finds, and who pays for it.
Verdict: the longest and most grounded pick. It works as a thriller and as a portrait of a community. It includes drug deaths, violence and a sexual assault.
Which one tonight?
You want clues you can solve along with the detective: A Good Girl's Guide to Murder, then The Westing Game. You want to finish before 2am: We Were Liars. You want a series that lasts until winter: Truly Devious or The Inheritance Games. You want the one that ruins you: Sadie. If none of those fit, the read-next quiz asks about mood instead of genre and does a better job than a list can.
If you care more about the pulse rate than the puzzle, the YA thrillers list has more chases and fewer suspect lists. For the adult versions of these books, the murder mystery shelf goes from Christie to the present, and the cozy mystery series round-up is for readers who want a body without the nightmares.
🔍Free on NanoReads: odd towns and haunted houses
All mystery →To be honest about our catalog: only one serial is actually tagged YA mystery, and a few more are YA books that turn on a mystery. That's a small shelf. These four are the closest match, and the first chapter of each is free.
Lila Finch: The Insurance Agent's Incurable Town
Adults: nobody has noticed In a secluded valley town, nobody has aged or fallen ill in forty years. During a routine audit, the insurance agent who covers almost everyone there finds the same teenagers enrolled in tenth grade since the 1980s. It's the only serial on our shelf tagged YA mystery, but the sleuth is an adult, and the premise reads like a cozy small-town mystery. Picture the Truly Devious cold case with a policy file in place of a school archive. Open the audit in chapter 1, free.
The Silver Key
Adults: never found her Elyra Solenne is eighteen. Her mother disappeared ten years ago with no body and no witnesses, and all she left behind was a key. Of our four, this one's the closest to the "adults already failed" group. It's also tagged romantic fantasy, forbidden romance and ghosts, so expect a supernatural answer rather than a police-procedural one. We haven't confirmed how much romance or heat the later chapters have. Chapter one of The Silver Key is free to read.
The A-XIS Initiative: The Nightmare Begins
Adults: call it a myth A mansion in upstate New York that should have fallen down decades ago. The locals say it's haunted and scholars say it's a myth. The mystery is what happened in it. Its tags are YA sci-fi and superheroes, so the solution isn't going to be a butler with a candlestick. Step into the house, chapter one is on us.
1313: Aces & Eights, Book 1
Adults: sent the squad in Mostly sci-fi horror: a floating fortress over a flooded Louisiana, and a portal above the ruins of New Orleans that lets out half-machine Martian scavengers. It's also tagged mystery, and time travel and parallel worlds are part of its world, but read it for the monsters, not the clues. Start 1313 free.
Two other YA serials our system matched to this page, American Patriotism and Ash and Bones, aren't mysteries, so we left them out. If a haunted house pulled you in more than the whodunit, the horror books hub is the better next stop. If you liked the kids-versus-the-system part, try the YA dystopian list.
Questions readers ask
What age are YA mystery books for?
Most are marketed at 13 and up, with 14 to 18 year-old leads. On this list, The Westing Game suits readers as young as ten. Sadie and Firekeeper's Daughter are better for older teens because of their subject matter.
Are YA mysteries fair-play, or can you guess the ending?
It depends on the book. A Good Girl's Guide to Murder and The Westing Game put the clues in front of you. We Were Liars and One of Us Is Lying depend more on hidden secrets, so you're less likely to solve them before the reveal.
Do I need to read the Good Girl's Guide series in order?
Yes. Each sequel depends on what happened before, and the later books pick up threads left in the first. Truly Devious and The Inheritance Games also need to be read in order, since book one of each leaves the main question open.
Is there romance in these books?
Some, and it's light. Pip and Ravi's slow build is part of the fun of A Good Girl's Guide to Murder. The Inheritance Games has a real love triangle. None of these books has explicit sex on the page.
