Rachel Payne's training as a demon hunter begins with a crash course in demonology and hand-to-hand combat. Father James has no choice but to expedite her initiation as the Sonoma County Fall Carnival is beginning. The underground demon hunting network, operated by the church, needs Rachel to help track down a demon that annually possesses humans in order to abduct and murder innocent patrons of the carnival. What Rachel doesn't realize is just how dangerous the work is, and her involvement puts herself and her family at risk. And, Rachel and her sister are reunited with Ansel, an old family friend. With an odd familiarity about him and a secret revealed by the demon-possessed clown, Rachel is close to discovering a deadly family curse.
