If you are looking for an erotic story that focuses on authentic BDSM, this has a lot to offer. The rules, the psychology, the logistics of the scenes and lifestyle are intelligent, well-written, and accurate. The author knows her subject matter.If you're new to BDSM, this is a great toe-dipper. You can learn right along with the curious, open-minded heroine. There's not any over-the-top, cringe-worthy moments. While the tone is erotic, there are a modest number of scenes with actual intercourse. This is more an exploration of trust and exchange of power, and less about kinky sex.If you prefer dark and forbidden, this isn't it. If you want romance and soul-depth love, this is not an erotic-romance. The words are spoken in the HEA conclusion, but I never felt the passionate, live-or-die connection between the MMs and F. That said, this book is fascinating and different, and most importantly, entertaining.
