Inside an ancient temple in the mountains, fifteen-year-old Zira trains in the martial arts to become a warrior priestess who can defend the faith of the Ruan people. Bearing a scar on her face from the fire that killed her parents, the orphaned Zira is taught to distrust the occupying Sedornes. Terror strikes when the forces of the tyrannical Sedorne king destroy the only home she knows. To survive, Zira must unravel the secrets of her identity, decide her people's fate — and accept her growing feelings for a man who should be her enemy.
