Sometimes going home again is a lot like going to hell….
Demon Frenzy by Harvey Click

Note: even though it has a sequel, Demon Frenzy is a complete stand-alone novel.

Sometimes going home again is a lot like going to hell.

Searching for her lost brother, Amy Jackson returns to her isolated hometown in the Appalachian Mountains. But Blackwood has changed. Now it’s run by a mysterious drug lord who has something more lethal than guns to protect him. He has demons—more vicious, venomous demons than even Hieronymus Bosch ever dreamed of—and after Amy witnesses an unspeakable atrocity he unleashes all the frenzied furies of hell against her. Soon she is stalked by snakewalkers, herky-jerkies, toadfaces, listeners, harpies, centicreepers, and the sinister crying man, who weeps while he torments his victims.
