Beware of the dark. You might like what you find. . .

Ruth Collier has always felt like an outsider, even as her father rains fire and brimstone from the church pulpit. In Bottom Springs, his word is as good as law. But there are things the townspeople fear more than God, like the Low Man, a vampiric figure said to kill sinners in their beds on moonless nights.

When a skull is found deep in the swamp, a hunt for the Low Man begins. Suspicion turns to Everett, Ruth's oldest friend, with a dark past. As Ruth and Everett grow closer, Ruth begins to unearth the town's secrets, determined to discover the truth.

But as the line between good and evil grows ever thin, how far will Ruth go to save the person she loves most.
