Not a bad read. There is a lot going on. At the end of the previous story, we find out that Don's ghost is not quite ready to leave. There is some stuff going on with Cat's former team. Cat, Bones and the gang fight off the ghost of a former witch hunter. You have most of the characters you have come to love, no Vlad, Mencheres, Juan or Dave though.
I can't wait to see how Tate handles some of the issues going on with the team in the next book. Also, what Don figures out either. He is also keeping something from Cat that is really going to bite one of the two in the ass at some point.
