Species boundaries blur when Cat Turner is the sole survivor of Sazi serial killer Jack Simpson's latest attack. Because of his history with the madman, Sazi wolf Raphael Ramirez is assigned to monitor Cat and see if she survives the change and if she remains sane. If she does, despite the fact she will be feline, he will be her teacher in coping with this new world. He will also be her protector from the insane man who is now obsessed with her and with completing his macabre task.

With every new entry in the series, more of the Sazi culture unfolds, revealing new complexities. Combined with the thriller and romantic aspects, this makes for a compelling read that will appeal to a wide variety of readers. The author's attention to detail is greatly appreciated, as is the way they show us the story without being heavy handed in the world-building.
