Keita Sage and her best friend Carli each have a mission: to find and protect their family and bring them home. The problem? The people they seek are leading opposite sides of a heated war. Keita's betrothed is trapped inside a foreign kingdom until his brothers return from war. She's determined to reunite her new family, but entering the chaos of the battlefield is twice as dangerous for her. Her brothers-in-law are fighting Coles, who manipulate heat, and she has both a natural weakness and a personal fear of fire. Carli can protect her, but she's searching for her long-lost sister, the Cole's new queen, no matter what atrocities her sister has committed. Keita and Carli need each other, but only one side can win a war.
