A duke's daughter once propelled her husband to become a legendary general, only to face betrayal and execution at the hands of him and his mother. Reborn from the ashes, she returns with a steely resolve and a heart of ice. Methodically, she dismantles those who wronged her: vanquishing her cunning half-sister, executing her malicious stepmother, reclaiming her mother's stolen dowry, and ensuring her treacherous husband and his favored concubine meet their end by her sword.
