Ten years ago, the mass suicide of the cult known as the Flock shook the small, rural town of Lola, Michigan. This was just weeks after one of their members, Laurel Tai, a local pageant queen, was abducted.

Naturally, the town blamed the sole survivor, and Laurel’s best friend, Claire Kettler. 

But Claire has no idea what happened, and can’t get answers to her questions because the cult leader is nowhere to be found. Ten years later, podcaster Arlo Stone wants to uncover the truth, and this spurs Claire back into action.

But can she find out the truth without spilling her own secrets before history repeats itself?

But the house harbors dark secrets, including the real reasons it was left behind in the first place. Kristen is trying to keep her colleagues calm, but it doesn’t seem to be working.

There’s a storm raging, which means the one access road to the rest of the world is blocked off. And it must mean the murderer is somewhere on the mountain.

As Will and Sara begin their investigation, they quickly realize that everyone is lying; about who they are, where they were, all of it.

Can they untangle a decades-old web of lies to discover what happened to Mercy before the killer strikes again?
