Kay's new friends pray together . . .and slay together.

When Kay reluctantly agreed to join the youth group at Stone Mission Church in Orange County California, she expected the Jesus talk and the dorky singalongs and the colorful posters about dodging temptation. What she didn’t expect was to stumble on her youth group leaders, Meg and Cortland, in the middle of a read-deal exorcism. Turns out they’re both soldiers in a secret organisation of demon hunters in a war that’s heating up, and even if Kay wanted to stay on the sidelines, she doesn’t have a choice – she’s a “Blight,” a human who demons can’t possess, and apparently that’s made her a target. Will Kay find her place in a world that’s so much more God-fearing and monster-fighting than what she’s used to? Or will a pack of demons use Blights like Kay as the key to starting some real big trouble?
