Fool Moon - Jim Butcher

Fool Moon is book two in the Dresden Files series. This time Harry is up against all four known types of werewolves and discovers a new one in the bargain. He and Murphy are still at odds after the problems in Storm Front, and Harry even becomes a suspect in what the press is calling the lobo killings. Throw in the Chicago mob and Harry has his hands, or paws, full. Highly recommended.
