Gabriel Braven is destined for a great love, but he does not believe it. His parents had a storybook romance… until a freak ocean storm robbed them of their lives and left him alone to be raised by his grandmother. With their deaths, Gabriel’s adoration for the sea turned to fear, and his belief in happy-ever-afters turned to dust. Gabriel vowed to never set foot in the ocean again and to never believe in love.

Gabriel should have drowned twice in his life, but he survived. Casillus Nerion, his beautiful merman savior, tells him the reason for this is simple: Gabriel is a merman. Long ago, a Braven ancestor fell in love and had a child with a powerful merman. This child did not inherit the Mer gifts, but Gabriel has. Despite seeing inexplicable physical changes to his body when he gets wet and having trouble breathing when there is plenty of air, Gabriel’s head tells him that Mer, like love, do not exist.

As Gabriel struggles to cope with the three days he has left on land, a new complication arises. His grandmother’s lover, the enigmatic archaeology professor Johnson Tims seems to know more than he should about Gabriel’s transformation into a merman. Gabriel’s lifeline is his own lover, Casillus Nerion, prince of the ocean-dwelling, immortal Mer. Life on land is becoming more and more difficult, but their loving mental connection grows with Gabriel’s trust in what he is becoming.

Gabriel's inevitable transformation into a merman brings him both great joy and great sadness. Though he must soon leave his human family, he is eager to experience the beauty of Emralis, the Mer city, together with his water-dwelling lover, Casillus.

Gabriel Braven knows his destiny, but is he willing to face it? Gabriel has only one day left on land before moving to the wondrous Mer city to live forever with his true love, Mer Prince Casillus Nerion. He wishes his greatest challenges were giving up making love on land with Casillus and telling his beloved grandmother that he is a merman. But ex-soldier Johnson Tims has other plans for him.
