Skin Game by Jim Butcher, 454 pages
For everyone that doesn't read them the Dresden Files are about a wizard named Harry Dresden. It follows him as he defends his beloved city of Chicago against crime and the supernatural realm. The series started with Storm Front in 2000 and with Skin Game has reached 15 novels.
In this latest adventure Harry is forced to team up with an old adversary by Mab. It also brings back some characters that we haven't seen in awhile. This book, and most of the series cannot be read as a stand alone, so if you want to read it pick up Strom Front and start reading. You won't regret it.
