The night before I was supposed to stand beside Lucius Corleone at the altar and become his wife, he sent me a message. Sienna was pregnant. According to the family code, her child would be the first legitimate heir to the Corleone name. So Lucius ordered me to leave Sicily for three years—and tell everyone I had broken our contract first. For eight years, I had been his shadow. I wiped away his blood, buried his crimes, protected his business, and waited for the day he would finally bring me into the light. But now, he said Sienna belonged in the sunlight. I stared at the message, my hands still burning from scrubbing away the evidence of his latest murder. Then I typed back one word. "Understood." A second later, Sienna's official wedding announcement appeared on the Corleone family's private network. Apparently, she couldn't even wait until morning to wear my ring.

How dare you make a flashy appearance while driving a car that belongs to my family!" I take a deep breath and explain coolly, "This is my car. I don't know what you're talking about." The next thing I know, Sienna grabs a ledger and hurls it at my face. She screams at me, "You used my family's money to buy this car, and yet you have the gall to claim that it's yours? "I'm my mother's actual child, and yet you've leeched all the good things from my family, you filthy bitch! I'll have you know that the hardships that Mom went through for nine months of pregnancy will be converted into a maternity fee of a million dollars! Now hurry up and transfer the payment to Mom's bank account!" I merely sneer at Sienna before pulling out my phone and calling her mother, Molly Dawson, "Your daughter demands that I give you a million dollars' worth of maternity fees.

Jordan Carter has made a career out of defending the kind of clients everyone else is afraid to touch—without ever crossing her own line. So when a sealed, high-dollar retainer lands on her desk tied to Mercer Holdings, she expects a rich man’s mess and a clean paycheck.

If she protects him, she’ll become complicit in a secret that was never meant to survive daylight.
