"When cynical, gothy Kay lets her mom talk her into joining the youth group at their church, she's prepared for the dorky sing-alongs and the cheesy slogans about dodging temptation. What she isn't prepared for is walking in on the clean-cut youth group leaders, Meg and Cortland, in the middle of a real-deal exorcism. Turns out these wholesome Christian teens are demon-hunting soldiers in a secret war that's heating up fast, 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 that makes her a target. But Kay's in good hands with her new friends--for them, fighting literal demons is all in a Sunday's work!"-- Provided by publisher.
