The last thing patrol cop Kate Prospero expected to find on her nightly rounds was a werewolf covered in the blood of his latest victim. But then, she also didn't expect that shooting him would land her in the crosshairs of a Magic Enforcement Agency task force, who wants to know why she killed their lead snitch. The more Prospero learns about the dangerous new potion the MEA is investigating, the more she's convinced that earning a spot on their task force is the career break she's been wanting. But getting the assignment proves much easier than solving the case. Especially once the investigation reveals their lead suspect is the man she walked away from ten years earlier-on the same day she swore she'd never use dirty magic again. Kate Prospero's about to learn the hard way that crossing a wizard will always get you burned, and that when it comes to magic, you should never say never.
