Storm Front by Jim Butcher

Hmmmm. If I had to pick my favorite wizard named Harry, it wouldn't be an English schoolboy. Harry Dresden is a wizard, living in Chicago and working as a private investigator. He gets called in on cases with which the police need help, cases that can't be solved by the usual methods. This book, and every book in the series, grabs you from the beginning and won't let go until the last word. Suspenseful and surprisingly funny, I enjoy every page, every sentence, every word Jim Butcher writes.
