Something changed for Rhya Fleetwood in the battle of Fyremas. Her untrained power feels both heavy with grief and volatile, crackling with each pulse of her simmering rage. Caeldera lies in ruins. Her friends are dead or wounded. And Pendefyre, their newly crowned king, is shutting her out. The Remnant of Fire needs all his focus for his kingdom, his people, and-perhaps more than anything-his insatiable need for revenge. When a twist of fate leads Rhya to the last place she expected-the Water Court-the novice wind weaver is forced to confront the limitations of her power as well as her increasingly complicated relationships. For enigmatic King Soren of Llyr is as different from Penn as sparks are from the sea. The more insight he offers into the maegic that binds them together, the more confused Rhya feels-about her future as a Remnant, about her deepest desires, and about her role in the coming war. Enemies circle close, ready to strike. And if Rhya isn't careful, she'll lose more than just her heart. She'll lose her life.
