This was the second one of the series. Still can't quite be sure what the heck is going on. I read the first two in the period of less than 2 months. And I did not read them back to back. I also read Furies of Calderon also by Jim Butcher, so I seem to be getting into the author. 
 So this one... There was a good amount of detail about the mythos that were being worked with in this story, but not so much that it was something that bogged down the story. It talked about where the ideas (at least in the universe talked about) are coming from. (view spoiler)[So... There are books after this one, with the same main character. Yep, they take place after this one... (hide spoiler)] Looking forward to the next ones.
