It's quite clear Carew did her homework -- the references to tantric sex and the Kama Sutra are quite accurate, as is the basic hypnotic trance induction. Hanna, Grey and J.M. are multidimensional and sympathetic characters. The sex scenes are varied and include threesomes, toys and leather/bondage, and the story is endearing. Fans of traditional romance may be surprised at the twist to the typical happy ending, but it really does fit with the rest of the story.
