In her past life, when her legitimate sister became pregnant, Gabrielle was sent to her brother-in-law as a bedchamber concubine. On the very day her sister gave birth, she was silenced and lost her life. Reborn, Gabrielle plots every step carefully. She wins over her powerful father-in-law and secures her marriage into the Duke’s household as its rightful mistress. Then she reclaims her status as the legitimate daughter and ruthlessly crushes those who wronged her—until the heartless schemers are left crying and begging for mercy.
