His Sea Goddess — Marisa Chenery

Book four in the Goddess Revealed series.

After a near miss with a shark while diving in the Red Sea in Egypt, Jarrett is rescued by a dolphin and unwillingly dragged to an underwater chamber. But it isn't just any dolphin. Wounded and unsure of his surroundings, Jarrett watches in awe as the dolphin shifts into a beautiful woman he is unable to resist.

Hatmehyt, an Egyptian goddess, was drawn to the man swimming near the reef while in her dolphin form, but soon realizes Jarrett is her mate. Unable to thrive on land, she has to make the painful choice to either keep him with her or let him go to the surface when the shark bite he received threatens his life.
