Five days. Twenty strangers. No way out.

The rafting trip was supposed to be the adventure of a lifetime. But Kaia's starting to think she made a mistake.

Because ever since the whispers about Camas Creek began, all she feels is dread.

Seven years earlier, a guide murdered a group of rafters on this same isolated stretch of water. The killer's body was recovered downstream-but the true-crime community has never stopped asking questions.

And for good reason.

The incidents start small-a flipped raft, missing supplies, and screams in the night-but the pattern is sickeningly familiar. And with eighty-four miles of whitewater until any sign of civilization, safety has never felt so far away.

Kaia suspects that one of the guides is lying. One of the guests knows more than she's saying. And somewhere on this river, someone is planning to finish what started at Camas Creek.
