I really enjoyed this book, and it was a lovely way to spend a warm summer afternoon. Harry Dresden is a wizard living in Chicago trying to eke out a living. He sometimes does consulting work for the local police force. They call him in to investigate some murders that were done by magic, and he gets entangled in some nasty stuff and has to figure out how to get out alive. This is the first in a series, and I'm looking forward to reading the others.
One review that I read said you'd probably like Jim Butcher's work if you like Laurell K. Hamilton and Tanya Huff. I am not a fan of Laurell K. Hamilton -- her stuff is too violent for me -- but I am a big fan of Tanya Huff, and I can see some similarities. (Blood Price, Tanya Huff's book about a tough-talking Toronto P.I. and her vampire sidekick, was recently made into a Lifetime TV series. The series is okay, but Huff's book is better.)
