Magic Under the Witching Moon. Two-Natured London 5.5. - Two-Natured London, #6

Human DS Adrian Moore believes he has learned everything there is to learn about the two-natured around him. But when a naked, moon-worshipping goddess shows up in his bedroom night after night, he admits he has no idea what to make of it. Other than that he wants her with maddening lust. Having escaped black witches keeping her and her coven sisters captive, Raven Fontaine finds safe haven with Adrian-in form of a cat.
If only the full moon wouldn't force her back into human every night, things would be perfect. Although, she has to admit that her human form fits his form rather pleasantly. The need to get her coven sisters freed forces Raven to confide in Adrian, who is more than capable of helping her. But the black witches are on her tail-literally. Can he keep her safe? And what does it mean when a New York cop starts to think that London might be home after all, as long as he has a certain witch by his side?
