This book is one of the very few ethnographies existing about people who live in intentional power exchange relationships as a significant facet of their personal lives. It was groundbreaking when it came out, and to my knowledge no work has since come close to sharing D/s relationships through the participants' eyes in quite this manner, It is a stellar work of sociology for the bdsm community, and well worth reading for anyone who wants to gain some insights into why people choose to do D/s and erotic power relationships.
