Cursed to Be His

To my family, I was fat, cursed, and unwanted. When my adopted sister abandoned her comatose mafia fiance, I took her place: his soul had promised me $200 million. Months later, I had transformed, and he woke up. My sister tried to steal the credit, but he remembered everything. Now I stand beside the Don, and the dead are warning me of a traitor at our wedding.
