Perfect for readers of Riley Sager and Grady Hendrix, a chilling new read from the New York Times bestselling author where a diabolical modern twist on Friday the 13th meets Yellowjackets at a summer sleepaway camp isolated in the woods of Oregon.

There are always stories told around the fire at summer camp—tall tales about gruesome murders and unhinged killers, concocted to scare new arrivals and lend an extra jolt of excitement to those hormone-charged nights. At Camp Luft-Shawk, nicknamed Camp Love Shack, there are stories about a creeping fog that brings death with it. But here, they’re not just campfire tales. Here, the stories are real.

Twenty years ago, a girl’s body was found on a ledge above the lake, arms crossed over her heart. Some said it was part of a suicide pact, connected to the nearby Haven Commune. Brooke, Rona, and Wendy were among the teenagers at camp that summer, looking for fun and sun, sex and adventure. They’ve never breathed a word about what really happened—or about the night their friendship shattered.

Now the camp, renamed Camp Fog Lake, has reopened for a new generation, and many of those who were there on that long-ago night are returning for an alumni weekend. But something is stirring at the lake again. As the fog rolls in, evil comes with it. Those stories were a warning, and they didn’t listen. And the only question is, who will live long enough to regret it?
