Fortunately, when I was at Whole Foods, the guy I worked with the most had just begun reading Dresden Files and upon finding I was a fan would talk to me about the chapter(s) he'd read the night before every day. It was like my very own refresher for the series. I did re-read Skin Game myself, though.
But since Peace Talks apparently has a cliffhanger, I miiiiiight hold off and just get the next Peter Grant book instead because oh man Broken Homes was so good.
