"Ex-boyfriend's mom" was all I needed to hear to be interested in reading this. Finding out it was not intentional did not make the story less juicy. A newly single Nyx (FMC) finds herself going to a BDSM club. Not only is she at the club, but she also feels alive for the first time after a session with its owner, the other FMC, Ax, who is a touch-me-not. The author notes right at the beginning of the book that "This is not an accurate portrayal of the BDSM community," so you have to take that into account. This book was spicy, had aa decent story and a nice little plot twist.
