Khosa was born to be fed to the sea, to prevent the kind of wave that once destroyed the Kingdom of Stille. She can't be sacrificed until she produces an heir, but human touch repulses her-- except for the touch of the Indiri. Dara and Donil are the last of the Indiri, a native race with magic that's a force of nature. Witt is leader of the Pietra, the fierce warriors who are now marching on the Kingdom of Stille; to ensure the survival of his people, he's prepared to conquer every speck of Stille's soil. Vincent stands to inherit the throne of Stille, and is torn between protecting his kingdom and protecting the girl whose fate is tied to its very existence. But the rising sea calls for its Given, and Khosa is destined to answer.
