True Detective meets H. P. Lovecraft in this mystery by the acclaimed author of Chaos as a cop investigates bizarre murders in a snow-bound small town.

It begins with a freak snowstorm in May. Hit hardest is the rural town of Colby, Connecticut. Schools and businesses are closed, powerlines are down, and police detective Jack Glazier has found a body in the snow. It appears to be the victim of a bizarre ritual murder. It won't be the last. As the snow piles up, so do the sacrifices. Cut off from the rest of the world, Glazier teams up with Kathy Ryan, an occult crime specialist, to uncover a secret society hiding in their midst.

The gods they worship are unthinkable. The powers they summon are unstoppable. And the things they will do to the good people of Colby are utterly, horribly unspeakable . . .
