This was an absolutely great read, and I would recommend it to pretty much anyone that has even a tiny interest in urban fantasy. It's all very light hearted and the narrator has a great voice. 
 The first few chapters are really the best, it has a very strong start. It's not that it drags as it goes on, it's just that the voice of the narrator, to me, was best when it was explaining things (yes, I found the exposition dumps fun to read!), and obviously as the book progressed, less things needed explaining, and it was more about the actual plot. Which was fine. 
 Either way, a great, easy read!
