Ten-year-old Ella lived as a slave in a run-down tavern, until a parchment notice searching for the werewolf duke's missing daughter changed her fate. With her last two copper coins, she boarded a night coach to Blackstone Castle, and was reunited with her cold yet deeply devoted wolf-king father and the gentle duchess. From an abused child who feared being whipped for dirtying a carpet, she became a noble werewolf princess. Under her parents' boundless love, Ella gradually let down her defenses and healed the wounds of her childhood. Meanwhile, the culprit who had kidnapped her all those years ago for a few gold coins would face the werewolf family's merciless fury, tearing everything apart in its path.
