The Curse of Brimstone (The Curse of Brimstone #6)

Nothing is creepier than possessed children. Wait, no, possessed dolls. Those are worse. Anyway, our heroes Joe and Annie find themselves under assault from a horde of possessed kids, all under the command of the mystical baddie Slackjaw. In reality, Slackjaw's a possessed child himself, so it might be time to call in Brimstone for an exorcism. Unfortunately, Joe's having a crisis of conscience because he doesn't want to fight children, even if they're possessed by the devil. So how do you stop a child-devil army without hurting the innocent possessed?
