With all the intensity and whiplash turns of Sharp Objects and One of Us Is Lying, this engrossing psychological thriller by New York Times bestselling author Lauren Oliver is an unforgettable, mesmerizing tale of exquisite obsession, spoiled innocence, and impossible friendships.

It's been five years since Summer Marks was brutally murdered in the woods.

Everyone thinks Mia and Brynn killed their best friend. That driven by their obsession with a novel called The Way into Lovelorn the three girls had imagined themselves into the magical world where their fantasies became twisted, even deadly.

The only thing is: they didn't do it.

On the anniversary of Summer's death, a seemingly insignificant discovery resurrects the mystery and pulls Mia and Brynn back together once again. But as the lines begin to blur between past and present and fiction and reality, the girls must confront what really happened in the woods all those years ago-no matter how monstrous.

• A Haunting Whodunit: Five years ago, Summer Marks was murdered and everyone blamed her best friends, Mia and Brynn. Now, a new clue forces them to ask: if they didn’t do it, who did?
• Twisted Friendships: Torn apart by suspicion and long-buried secrets, two former best friends must team up to clear their names, confronting the monstrous truth of what they all became in those woods.
• A Book within a Book: The key may lie in The Way into Lovelorn, the fantasy novel the girls were obsessed with—and the fan fiction they wrote that seemed to predict the murder in chilling detail.
• An Unreliable Past: As Mia and Brynn dig deeper, the lines between their fantasy world and reality blur, making them question what really happened that day—and if they can even trust their own memories.
