Though terrified of the ocean, Shelly Merdock finds herself alone in Cancun on what should have been her honeymoon–but not for long. A handsome and very naked man strolls out of the surf and onto her patio, claiming to be her lifemate. He also believes he’s a merman–the great, great grandson of Poseidon no less–and insists they have sex in the water within twenty-four hours to complete the marriage ritual. Crazier still, Shelly actually considers his offer. Who could resist? But can she place herself in the hands of the sexy stranger, beyond a night of shared intimacy, and shed her fear of the water to live with him in his palace under the sea?
