On the night before the wedding, my fiancé suddenly asked me to give up the ceremony for his first love, Sofia. I turned it down cold in my former life, only to become the Chicago mob’s godmother at a lavish wedding. When Sofia heard the news, she was heartbroken and jumped into the sea to take her own life. Vincent blamed me for Sofia’s death. For the next thirty years, the words he said to me most often were: “Elena, if I had married Sofia that day, she wouldn't have died.” On his deathbed, he told our children: “Don’t bury me with Elena.” The year after he died, I fell gravely ill and passed away. When I opened my eyes again, I was back on the night before the wedding. Over the phone, Vincent's voice came again: "Sofia needs this title more than you do. Everyone knows I love you, so they respect you—but Sofia's different. She's just a poor orphan girl..." Before he could finish, I calmly replied, “Fine, I agree.” I turned and signed the papers to cut ties with the family. I flew to Sicily, home to the Salk Institute that I had always looked up to. In this life, I refuse to be his appendage.
