After the bishop’s younger sister, Martha Mast, makes a plea for help, the holy man asks a favor of Sheriff Serenity Adams—one that will take her on a journey from the farmlands of the Midwest to the Kentucky wilderness.

In the small and isolated town of Possum Gap, nothing is as quiet—or as safe—as it seems. Navigating this new landscape, Serenity teams up with the local sheriff, Sadie Mills, in a race against time to unravel the truth about a missing Amish boy. But with new evidence emerging that links the boy’s disappearance to a voodoo cult and a hillbilly clan, can Serenity truly trust her Kentucky counterpart? Within the surrounding shadowy mountains, evil is spreading like wildfire, and Serenity finds herself fighting an unstoppable force as she digs up the secrets of the past.

Alone in unfamiliar territory, lost among strangers, Serenity’s luck may have finally run out.
