The other reviewers comment that this is a fairly frustrating book and I would have to agree. I very much like the Toby daye character and the secondary personalities as well as the fae world that the author has created. Rosemary and Rue was a great opening novel.
However this book really struggled with the fact that it was set pretty much entirely in the one building where everyone was being killed off, one by one. By the second death, I was seriously wondering whether anyone had ever seen a horror movie as they continually broke the cardinal rule of not going off by themselves in the dark - maybe they were all just too stupid to live? The story line with Alex and his sister was also very obvious and the fact that Toby continually failed to pick up on it undermined my confidence in her as a detective. Also I am not sure that she actually added much to finding the killer as it pretty much came down to who was the last man standing.

Am hoping the third book will be better.
