The powerful Kingdom of Valens continues to fight its never ending war against its hostile neighbors. Nara, the daughter of one of the kingdom's military commanders, can only think about achieving glory on the battle field. She is bright, talented, and determined. The only problem is she's a girl. Nara's brother Herod is blind. All boys are expected to join the army, and Herod, despite his blindness, is no exception. In spite of his father's expectations, Herod knows that he will be incapable of completing his duty and thus upholding his family's honor. Hungry for adventure as well as her father's approval, Nara eagerly takes her brother's place, completely ignoring the kingdom's strict gender based roles and traditions. As Nara trains at the military camp under her brother's name, her natural talent and courage soon catches the attention of everyone around her. But the more she shines, the quicker her true identity reveals itself along with the resulting consequences.
