1.) Skin Game
2.) Changes
3.) Cold Days
4.) Summer Knight
5.) Dead Beat
Jim is one of the rare writers who gets better as the years go on and his books get better, too, but I have a big place in my heart for Summer Knight, because it was a marked jump in quality from the first three books. Dead Beat is just great overall. And Skin Game has been, so far, the best book in the series, with the best prose, the best character moments and the most fun plot.
