Storm Damaged — Kerry Adrienne

In a world where humans don't know mermaids exist, Mari leaves her home in the ocean to escape her mother, her betrothed, and her tribe's expectations in order to make a go of independence on land. Chase, former Navy diver and self-appointed curmudgeon-who-isn't-worthy-of-love, lost his brother in a freak diving accident and now fears the ocean he once loved.

Mari's a mermaid with a plan. She has to get the sexy bartender, Chase, to remain on the island so she can get him into her bed. Trouble is, he's afraid of the water and there's a hurricane coming. But with Mari's betrothed on the rampage over a centuries-old vendetta, the storm isn't the worst thing they'll have to face.
