Very good modern urban fantasy detective Noir 
 Picks up a few months or a year after the previous book. References are mention and previous characters are shown but this is a stand alone Harry Dresden story. Modern and interesting take on the werewolf mythos but this is NOT a book for children. People will die and other dark things will happen. 
 Everything that could go wrong does, there is no Deus Ex here. and Harry Dresden is put through The writing style is so detailed and descriptive it felt like I was feeling the pain along with him. 
 Characters feel very real and in depth. Like the previous book it continues to hint at the bigger world while taking it's time not revealing too much. I expect some of these threads will take a few books to resolve. Harry has to make some tough choices and there are consequences. 
 The main complaint I would have is that I can't tell how much of the references were from the first book or just used to make the world seem bigger. Maybe that is a good thing. 
 If you like Noir, modern Urban fantasy and not scared of a long series I'd recommend this book. Also if you like to see someone describe their experience with pain.
