Two if by Sea — Mellanie Szereto

Being spelled into a painting as a topless mermaid by an inept cousin couldn't have come at a worse time for witch Kata Macska. With only seven days in which to find her mate and conceive a daughter to carry on the family legacy, she fears failure until she discovers that her fellow castaways, hunky brothers Aaron and Adam Waters, are more than willing to share her love. The brothers are at a loss to explain how they came to be marooned on a tropical island with the woman of their dreams, but they make the most of her ability to change from a mermaid to a woman at night. Though they suspect that her family is somehow responsible for their predicament, they've both fallen for the lovely Kata and want nothing more than to spend the rest of their lives at her side. But are they her true mates?
