Angel Burns—a curvy, small town fire fighter with a mysterious past and a sharp tongue—has far more to worry about than her sexist jerk of a boss; she has a gang of demons out for her head. After Angel unwittingly stumbles into an ages old battle between good and evil, long dormant powers are awakened within her, and the denizens of Hell want payback. The only way to keep them from unleashing Hell on Earth is to lock each demon inside a Gutenberg Bible. Angel, looking for vengeance of her own, plans to do just that. And—oh yeah—she has an axe.
