Hitomi Kanehara won one of the most prestigious literature awards in Japan with this book "Hebi to piasu." She was only 17 years old or something when she received this award. I happened to read this book and found this story was right on the BDSM topic, as the main character woman was a self-identified masochist who had an affair with a bisexual self-identified sadist. The descritptions and emotions going around the BDSM sexuality are quite visual and sensetional. I think it is worth taking a loot at when you get a chance.
so you knew about this book and even its topic?
I didn't know - maybe people who like BDSM already check this book then. It was in fact easy reading - big font and fewer pages. if you get a chance, please let me know. I read that in Japanese :)
