Maria Del Rey 
Pleasure Principle 

Sex is deviant. Disgusting. Depraved. Sex is banned. And yet despite the law, and the Moral Guardians who police it, a sexual underworld exists which recognizes no rule but that of desire. Into this dark world of the flesh enters Detective Rey Coover, a man who must struggle with his own instincts to uncover the truth about those who recognize no limits. Erotica, science fiction and crime collide in one of Maria del Rey’s most imaginative and explicit novels.
