Mermen twins Jaden and Chrys have been scorned all their lives by Atlantean society. The only one who cares about them is Prince Aurus. But when Aurus and Chrys fall in love, they leave Jaden an outsider. Secretly, Jaden wants his twin, but he keeps his sinful affection well hidden. After they are separated from Aurus, he is the only one who can comfort Chrys, even if only in a brotherly manner. When the Atlantean king concocts a plan to hurt them, Jaden and Chrys run away, and their paths cross with Aurus's again. This time, though, a strange force interferes in their lives. A dark, powerful beast that lives in the depths of the ocean calls out to Jaden, luring him toward its lair. With Jaden in danger of disappearing forever, Chrys and Aurus are faced with a choice, a realization, and a decision. Will mysterious Vaar finally help the three mermen see the truth, or will he end their very existences?
