Rory is an engaging character, and her reaction to Stephen's death is quite understandable. She is grieving, but also feels that she can actually bring him back. I really liked the information about Sid and Sadie, and their group in the 1970s. London was such a vibrant and edgy place at the time, that it's nice to see that brought into fiction. The magical elements all work out and seem realistic. The inclusion of London landmarks tied to death and spiritualism was interesting.
There are parts of this that are REALLY gruesome and a bit uncalled for, so this is not for the sensitive soul.
