Demon Rising by DeAnna Browne

In a post-apocalyptic world ruled by magicians and their demon pets, twenty-four-year-old Becca survives the dangerous streets by relying on her wits, her fists, and the limited goodwill of her boss, a local crime lord. When news comes of a fire back home and the family she left behind dead, she realizes her dark past has finally caught up to her. On the hunt for her missing sister, she must rely on Darion, a treacherous ex-boyfriend with ties to the local coven, for back-up. Problem is he’s a pyromancer who can’t be trusted. Will she escape the sticky web of treachery and deceit with her sister and her heart, or will she sacrifice it all to save another?
