Two months ago, Kai Monahan was bound by fire to a dragon warrior. Now she tells herself it was only a nightmare-until the flames inside her refuse to die. Back in the human world, Kai tries to reclaim a normal life. But her newfound magic burns out of control, and when Rhys's enemies uncover who she really is, he has no choice but to spirit her away to his hidden court of Eryri. There, among ancient grudges and dangerous whispers, Kai discovers that history remembers Rhys's father-and the Wingless mate whose rage ignited a war. Hatred runs deep, and one misstep could topple Rhys's reign before it ever begins. He cannot protect his people without her. She cannot master her power without him. But every secret they keep from each other sharpens the blade hovering at their throats. For the bond between them is no longer about fate-or desire. It is the spark that could set the world ablaze. And this time, there is no going back.
