Mermaid princess Mira is betrayed by her twin shark guards, who carve out her heart at the sea serpent's command — until her fated fiancé, the sea god, saves her. At their wedding, the traitors kidnap her and seal her memories with forbidden magic. But Mira breaks free, shatters their lies before the crowd, and watches every villain fall. Crowned sea queen beside her god, she rules the ocean at last.
