Golden Chevalier

Wrongly accused and left to die, a fallen queen opens her eyes ten years earlier—back at nineteen, just after her parents' deaths. Given a second chance, she swears never to be used again. To protect her family, she sets her sights on the empire's highest rank of knighthood: the Chevalier. Through relentless training and treacherous court politics, she forges herself into a true warrior—until the commander of the knight order appears before her, setting a new fate into motion.
