Six teens play an innocent game in the woods. But there's a traitor among them. And not everyone will make it home alive. From the author of Every Last Liar comes a thrilling story of survival.

In the middle of the night, Liv Walker is taken from her bedroom by two masked figures. As she's dragged into an unmarked van, she calls out to her family to save her… only to realize they are the ones responsible for her kidnapping.

They've made the decision to send her to Camp Smiling Skies, a wilderness therapy program for "troubled teens"… At least, that's what it says in the glossy brochure. In reality, it's a place filled with dark secrets, sadistic counselors, and no chance of escape.

Liv isn't sure things could get any worse, until one by one, people start to die—their deaths mirroring a seemingly innocent game of Werewolf the group played one night by the campfire.

Liv has already been betrayed by her family, but it seems like they're not the only traitors in her life. There's a murderer in the camp, and not everyone is getting out alive.
