Dresden Files: Summer Knight

His name is Harry Blackstone Copperfield Dresden. You can work magic with that name — he is not responsible for the consequences. When things take a strange turn, when that which is meant to be buried in darkness crawls into the light, when no one else can help you, call... Who? Him, Harry Dresden. His name is in the "Yellow Pages"… A new series of adventures of detective-wizard Harry Dresden, who investigates all sorts of magical mishaps in an alternate Chicago. This time fate has thrown Harry a challenging case: the Summer Knight, a mediator between the Summer and Winter courts of faerie, has been murdered, and the wizard Harry's mission is not only to investigate this case but also to stop the war shaking the worlds, earthly and otherwise… The series of novels about Harry Dresden holds a worthy place alongside such a well-known example of fantasy detective fiction as the series about Garrett, penned by Glen Cook.
