I love this series. Most series start strong, then fizzle shortly after, but not this one. Ilona Andrews does it right. In a sea of kick-a** heroines, magic, shifters and vampires, the Kate Daniels series stands out (and I'd say stands head and shoulders above the competition). Kate is not someone I would ever want to cross, but having her as a friend would be priceless. She is believable, strong but not invulnerable, and I'm always rooting for her and all of the friends she has gathered on the way. 
 The action is great - what I've come to expect in this series, and the stakes keep getting higher. I'll also call this one a relationship book, and I think that it comes at exactly the right place in the series. 
 I love the progression of the characters, their relationships, and I can't wait to see what happens next.
