Claire's five-year-old son has never let her hug him. Her husband Ethan is handsome, rich, and so emotionally frozen she's spent six years thinking he simply doesn't care. Then a vision hits her: she's going to die — and in the flash, Ethan is kneeling over her body, sobbing pearls into the ocean. Turns out her husband is a merman. Her son is too. Nathan has been keeping his distance because every time his heart races, his fins pop out, and his father told him Mom doesn't like fish. The day Claire finds out, Nathan is already packing his backpack and his pet clownfish, ready to leave before she can throw him out. She pulls him into her arms instead. Ethan, stranded overseas by a hurricane, swims home across the ocean. He walks through the door soaking wet and says, "Daniel's back. That desperate to divorce me?" The man swam through a typhoon and still opened with jealousy. When Claire was little, she wished on the sea every year for a merman. She kept lowering her standards. Turns out she never needed to.
