The first thing I did when I woke up in this life? I called my underboss and ordered fifty crates of the new Colt revolvers delivered to the estate. Let me rewind. In my past life, my stepmother Veronica and my fiancé Marco were sleeping together. She got pregnant with his bastard. To keep my father, Don Salvatore, from finding out, she deliberately sabotaged a family weapons deal. She let a rival crew intercept the shipment and used the chaos to lose the baby. Then she came home crying to the Don. "It's all Irene's fault. She was too greedy, too reckless. She insisted on that unsafe sea route. I was ambushed, I lost the child... our heir..." I tried to defend myself. But Marco stepped up and pointed right at me. "Irene Moretti, I am beyond disappointed in you. You've always been reckless, never caring who gets caught in the crossfire. But this, making your own mother miscarry just to chase a win? That's monstrous. I'm done with you. The engagement is over." My father lost it. In front of the entire family, he lashed me with a whip, a dozen strokes. Afterward, Veronica sweet‑talked him into shipping me off to marry into our rival family. They locked me in their basement and tortured me until I died. Only after death did I learn the truth: Marco was Veronica's lover all along. He only agreed to marry me so they'd have cover to meet in plain sight. Now I open my eyes. And I'm back. The very day Veronica "lost" her baby. Not this time, sweetheart. Not. This. Time.

“What could I possibly use you for?” Don Antonio asked as he walked towards her. He lifted her chin, his gray eyes staring deep staring into hers burning with a mixture of curiosity and desire.
