This was a breeze to read and with a main character still in her teens, this book qualifies squarely in the young-adult category. 
 The story is fairly good, but I strongly prefer Kim Harrison's normal books, targeted at an adult audience with a demand for more complex story lines and especially more developed characters. Madison has according to the story just turned seventeen, but there is not nearly enough maturity and experience to make her believable. 
 It was an OK read, but unless something changes I don't think I'll read any more in this series.
