Emma Montrose works for an investigative agency and has finally obtained her license, but for now, she is still their secretary.  Emma has been asking for a chance to prove herself, but today she is thinking not about being investigator but having a chance to sleep with one.  Today Emma turned twenty-five and for her present she really wants one of her co-workers.  It's never going to happen, but a girl can dream—can't she?

Jack Sullivan is more than a sexy and accomplished investigator, he is also a shapeshifter.  Like the owner and other investigators, Jack is a Taniwha, an aquatic animal that needs lots and lots of sex to help ease his animal.  It’s just Jack's luck that he has been teamed up with a rookie for his next case.  Not just any rookie either, but Emma their secretary, who has never hidden her attraction to him, and they have to go as a couple.  Even worse luck, the full moon is right around the corner and Jack will either need lots and lots of sex so he won't shift or he will become a rather ugly creature for a day.

Their case?  To check out an adult resort that is based on sex. Emma is determined to show Jack that she can be a sexy woman and a pretty good investigator too.  There is something seriously odd going on at the resort and it appears to be focused on Emma and Jack.  Emma seems to be finding out clues and Jack is having to work overtime to track down suspects and keep Emma safe.  The question now is will their cover hold or as the full moon comes closer will the cover become reality?
