She's a vengeful syren. He's the pirate who failed to save her. Now, they must work together to save the seas they both call home–and each other.

Brigid should have drowned. Instead, the sea claimed her as a syren, and vengeance became her only purpose. But when she recognizes the man drowning before her, she breaks every vow to spare him—and begins to question where her loyalties truly lie.

Caelum has spent his life fighting the bloody legacy of his father. Saving others is the only way he knows how to atone. But when he comes face-to-face with the girl he failed years ago—now a deadly syren—he must choose between duty and desire.

As darkness spreads across the seas, Brigid and Caelum are forced into an uneasy alliance. But when the syren queen drags Brigid beneath the waves for retribution, Caelum will risk everything—even his soul—for the chance to bring her back.
