Aislynn is a mermaid who has watched humans from afar for thousands of years. A negotiator for Neptune, she wonders, what it would be like to feel anything but especially passion the way humans do when they have sex. The truth is mermaids can't feel emotions of any kind and hot sex is one of those experiences she wishes for. When the opportunity to become a human - temporarily - presents itself, she takes it.
Finley McCormock is a hard-core, tough as nails divorce attorney who represents rich women leaving their husbands. He has no time to do pro-bono environmental work like his colleagues or to fall in love himself. Why bother? He knows how marriages end. But, his new housekeeper, as odd as she is, gives him a hard on he has to take care of. The good news is Aislynn seems more than happy to oblige. She is his sexual fantasy come true, from the mid-day office visit that includes a spanking session to the trip to Trinker's Sex Toys. Aislynn is willing to try anything.
But, when Aislynn's past catches up with her, Finley will have to decide if his attraction for Aislynn goes further than the surface of the water. Does he really want to get in deep with his mermaid?
