I bought the first one on a whim after watching the series a few weeks back, lets just say i finished the 9th in the series a couple of days ago.
I really really liked the Dresden Files, its Detective Noir, its got some cool magic crap in it thats explained fairly well, damn witty dialogue with some nice pop culture inclusions like the evil overlord list. The books build on each other which i like alot. Lots of action and oh shit moments. Its a definite good read.
