The spine-tingling horror of Stephen King meets an eerie mystery worthy of Sara Shepard's Pretty Little Liars series in Kate Karyus Quinn's haunting debut.

On a cool autumn night, Annaliese Rose Gordon stumbled out of the woods and into a high school party. She was screaming. Drenched in blood. Then she vanished.

A year later, Annaliese is found wandering down a road hundreds of miles away. She doesn't know who she is. She doesn't know how she got there. She only knows one thing: She is not the real Annaliese Rose Gordon.

Now Annaliese is haunted by strange visions and broken memories. Memories of a reckless, desperate wish . . . a bloody razor . . . and the faces of other girls who disappeared. Piece by piece, Annaliese's fractured memories come together to reveal a violent, endless cycle that she will never escape—unless she can unlock the twisted secrets of her past.

• A Chilling Case of Amnesia: She’s back after a year, but her memory isn’t. Annaliese knows she’s an imposter in her own life, but the truth of who—or what—she really is might be too terrifying to remember.
• Haunting Visions: Snatches of memory return, revealing a bloody razor, the faces of other girls who have vanished, and a desperate wish that started a violent, endless cycle.
• Body Horror Suspense: The entity wearing Annaliese’s skin is driven by a strange, dark hunger. As she fights for control, she uncovers a terrifying ritual that consumes girls piece by piece.
• Twisted High School Secrets: Returning to high school means facing the boy she was with the night she disappeared, suspicious classmates, and a past that won’t stay buried.
