Stephen King meets Tuck Everlasting in this eerie, compulsively page-turning tale of a girl haunted by the loss of her sister—and trapped by the mysterious power that fuels her small town.

Gardnerville seems like a paradise. But every four years, a strange madness compels the town's teenagers to commit terrible crimes. Four years ago, Skylar's sister, Piper, led her classmates on a midnight death march into a watery grave. Now Piper is gone. And to get her back, Skylar must find a way to end Gardnerville's murderous cycle.

From Kate Karyus Quinn, author of Another Little Piece, comes a mesmerizing and suspenseful novel that will thrill fans of Maggie Stiefvater's The Raven Boys and Brenna Yovanoff's The Replacement.
