Princess Meredith is sacrificed to the sea in a marriage meant to end a centuries-old war—only to drown on her wedding night. But the ocean refuses to let her go. Rescued by Sylvan, the brooding heir to the sunken throne, she awakens transformed, her veins humming with seawater and her fate tangled in the dark politics of the deep.

As Meredith uncovers the Sea Kingdom's true intentions—and her shocking connection to its power—she's forced to choose: return to the surface as a hollow, forgetful ghost of herself, or embrace the abyss and become something more. Something monstrous. Something divine.

But the sea loves nothing without teeth. And its price is her humanity.
