Summer Knight (Jim Butcher)

I'm not reading the Dresden Files novels in order, but I'm enjoying them a lot. Harry Dresden is my kind of hero: unreasonably strong and competent, but with realistic flaws and foibles and deeply concerned about other people. He is a wizard in modern-day Chicago, dragged into a war between the Summer and Winter Courts of Faerie that threatens the very existence of the Earth, not to mention the lives of everyone Harry cares about. In order to save the day Harry has to solve a murder mystery: who killed the Summer Knight? The Queen of Winter is the obvious suspect, but she's the one who hired Harry to solve the crime, so maybe not. As usual, Harry is helped out by an assortment of people: Murphy, the CPD cop; a pack of enthusiastic young werewolves; the mystical Mothers of Winter and Summer; and a small coven of changelings still balanced between the human and the faerie world. The action is nearly nonstop, and I enjoyed the ride.
