I'm kind of sad to just give this one two stars, because the premise is really good, and Kate Daniels is a likable character who deserves at least three stars on her own merits of awesomeness. 
 That said, I this book was something of a disappointment to me. 
 When I started it I was really excited as it's set up kind of like a cross between an early episode of Grimm and Winter's Bone (the whole mystery element and punchy dialogue reminds me of it) with sprinklings of the Mortal Instruments dropped in. But fact of the matter is, I felt the book didn't DO anything with the universe it set up, it was just like having really pretty background scenery and nothing substantial. Sure, I loved the descriptions, such as the fey lanterns replacing regular lights when the magic waves hit, and some of the little details like the phones only sometimes not working when the power went out and the reason behind that... However, as a story, it's pretty weak. It seemed like the authors (that's not a typo, it's co-written by a husband and wife, look it up if you don't believe me) had so little for their awesome main character to do they just sent her a number of "magical errands" until she figured out who the villain was. 
 And the whole subplot with DR. Crest seemed pointless... Any nitwit can tell Kate/Curran is probably gonna be end game in this series... 
 So yeah I dunno, I don't think I'll be continuing with this series; it just doesn't hold my interest enough despite it's dazzling potential. Pity.
