There is a lot of description in the first few pages, which sets up the story. I like the originality of the sleep-walking - it is an interesting angle and could be quite insightful if the research was done properly. But I don't think this is a book for me. Other than the sleep walking angle, I didn't find the many many many pages of description engaging enough for me to continue reading. The cover is uninspiring and typical for the genre, though it looks like a cover for a 'who dunnit?' book.
