In Cloud County, where music and Tufa, the otherworldly fae community, intermix, a monster roams the forest, while another kind of evil lurks in the hearts of men.
Young Tufa woman Kera Rogers disappears while hiking in the woods by Needsville. Soon, her half-eaten remains are found, and hunters discover the culprits: a horde of wild hogs led by a massive boar with seemingly supernatural strength.
Kera's boyfriend Duncan Gowen mourns her death, until he finds evidence she cheated on him with his best friend Adam Procure. When Adam's body is the next one found, who is to blame: Duncan or the monstrous swine?
As winter descends and determined hunters pursue beasts across the Appalachians, other Tufa seek the truth behind Adam and Kera's deaths. What answers will unfold come spring?
