This collection of Dresden short stories was kicky and fun. They are all prefaced with an introduction that lets you know what anthology they were written for, which books they come between/before/after, and generally the motivation or theme associated with it. There are funny and serious stories. There are some stories better than others, but overall it definitely adds nicely to the series.
Bonus star for the last story, which is a novella that takes place after Changes. The reason for the bonus story was that it was told through Karrin, who is one of my favorite characters in the series.
