God of wrath

I've been trapped by the devil. When Cecily Knight does a favor for a friend, going to the Heathens' violent initiation competition to get a lay of the land for a rival gang, she thinks she may be able to get away with it because she has a superpower: invisibility. She can slip through most situations unnoticed. But immediately, she realizes her mistake. Behind enemy lines on a night like that, she's done the opposite, and the devil has noticed her. Jeremy Volkov isn't really the devil, but he may as well be as far as Cecily's concerned.
