Okay. To begin with, I love noir, and Jim Butcher has done a good job with it in "Storm Front". That had me hooked right away. But he also seems to know his way around a good story of wizards and magic and all that comes along with that. So, yes, I liked the book very much. A few thoughts about story, characterizations, etc.
Characterization...Harry is great. It occurs to me that he is sort of the Jim Rockford of wizards. (If any of you have ever watched "The Rockford Files", you know that Rockford gets knocked around in just about every episode, just as Harry seems to do.) But that is a good thing. Okay, so Harry is, oh, a little irresponsible in some ways, maybe a bit dysfunctional. But he's a good guy; he has his priorities mostly straight, even though (like all good noir detectives) he tends to get himself in trouble with the authorities from time to time (another thing he has in common with Rockford). And with two sets of authorities to deal with (the cops and the Council), that plays an even more important role here. I don't want to stretch the Harry/Rockford connection too far, but it was something that definitely came to mind as I read. Some of the other characters were a bit on the stock side but, again, that's noir for you. It's almost required, it seems like.
Story...Interesting. Not too complicated. A bit formulaic...but noir is often that. I mean, how many noir novels of any kind don't start out with a seeming damsel in distress seeking out the detective, who doesn't figure out until it is almost too late that she's been hiding something all along?
Use of magick...Often novels like this don't work for me because I don't believe the magical elements. This one worked. I think it was because the magick didn't always work quite like Harry (or other characters, for that matter) intended for it to. Makes it more realistic, IMO.
