“I betrayed the only man who stayed faithful to me, and died by the hand of the father I worshipped.”​Olivia Luceron was the perfect tool. For years, she acted as a spy within her own marriage, feeding her father secrets to dismantle her husband’s power. Her reward? A cold dungeon, a mutilated body, and a walk of shame through the empire’s streets.​Her husband, Duke Matthias, whom she treated with nothing but icy indifference, died protecting her. Her father, whom she gave her soul to, was the one who ordered her torture.​Now, Olivia has returned a year before her death.​The platinum hair she lost is back. The scars on her chest have vanished. And Matthias—the man who kissed her forehead in a dark cell before facing the executioner—is still alive.​She doesn't seek his forgiveness. She doesn't even seek his love. In this life, Olivia has only one goal: to use her position as the Duchess to systematically destroy the Locron family from within.​She will be the “Perfect Wife” this time—a mask of ice to hide a heart of fire.“Dear Father, you taught me how to be a monster. It’s only fair that I show you what I’ve learned.”
