In her past life, Thalia, an Athenian noble lady, married into the illustrious divine-blood clan. She sacrificed everything for glory, only to have her life taken by her jealous sister Liza on the day of her consecration as High Priestess.
Reborn three years prior, on the day of the Coral Garland Suitor Selection Ceremony, she discovers Liza has also returned with memories of their previous life. Eager to seize the wealth, status and prestige once belonging to her sister, Liza picks the powerful aristocrat Acastos first. She secretly schemes to ensure Thalia’s garland lands on a destitute wandering fisherman, Pelagios.
Yet Thalia, who has seen through hollow glory, refuses to back down. She resolutely weds the poor fisherman mocked by the entire city. Abandoned by her family, humiliated by nobles, threatened with sacred fire punishment and ensnared in endless plots, the two grow to trust and love one another amid adversity. Every time Thalia faces mortal danger, Pelagios unleashes mysterious power far beyond any mortal.
When the tides rise, his true identity is revealed: the penniless fisherman is Triton, heir to Poseidon’s realm and Prince of the Deep Sea.
Upon arriving at the underwater palace, Thalia must overcome prejudice from the gods, trials set by the Queen of the Ocean, and relentless persecution from the goddess Apate. In the end, her kindness, bravery and unyielding spirit win the approval of all deities, and she is crowned the Pearl Queen. Meanwhile, Liza, consumed by her hunger for power, dooms herself to an eternal lightless abyss.
