I'm usually not a big fan of crime fiction, thrillers, or mysteries, but I am interested in Japan and Japanese writers, so I picked this book up. It was entertaining, although very twisted and disturbing at times which turned me off a bit. I guess I just don't like depressing books and this book had a sort of depressing tone throughout. However, the premise is really unique and chilling and it really gave a glimpse of the darker side of Japanese culture and of human relationships in general.
