Yellowjackets meets One of Us Is Lying in this masterful survival thriller from New York Times bestselling author Sarah Beth Durst.

"Formidably scary, Durst's survival/horror story is the stuff of late-night campfire legends. With three deftly drawn, powerful girls at the center, reading felt like I had found a crew of clever, loyal best friends, even as I stayed up long into the night, trembling with dread." -E. Lockhart, #1 New York Times bestselling author of We Were Liars

Claire's grown up triple-checking locks. Counting her steps. Second-guessing every decision. It's just how she's wired-her worst-case scenarios never actually come true.

Until she arrives at an off-the-grid summer camp to find a blackened, burned husk instead of a lodge-and no survivors, except her and two other late arrivals: Reyva and Mariana.

When the three girls find a dead body in the woods, they realize none of this is an accident. Someone, something, is hunting them. Something that hides in the shadows.

Something that refuses to let them leave.
