Old Blood satisfies my inner (or not so inner?) information whore. Though this story is about Pippa, it sheds a lot of light on what happened/is happening/will likely happen to Perry. And Dex! We get a little information on Dex--information that he would probably not willingly share otherwise. This novella ties up some remaining threads in both Lying Season and On Demon Wings. Which was good. I like the tying of threads and this answered some questions I've had rolling around in my head about Perry and her abilities throughout the entire series thus far. *thumbs up*
