He bought me for four million euros. Now he owns every breath I take. When my father vanishes with four million euros stolen from the Russian mafia, I expect a bullet. Instead, I get Viktor Volkov. Pakhan of the Paris Bratva. Forty-one years old. Glacial blue eyes. A black rose tattooed over his heart. And a contract that says I either marry him by morning—or his enemies finish what my father started. I sign. I swear I'll destroy him from the inside. But Viktor doesn't behave like a man who has bought a wife. He behaves like a man who has been waiting for one. He sets the code to his most secret safe to my date of birth. He gives me a book inscribed for my mother in handwriting eleven years old. He looks at me, in the firelight of a fortress on the Avenue Foch, like he has known me longer than I have been alive. Because, it turns out, he has. Because the night my mother died, eleven years ago, a thirty-year-old Russian officer in a hospital corridor swore an oath he has been keeping in silence ever since. And his uncle—the patriarch of the family I have just married into—is the man who ordered her killed. Some vows are written in ink. His was written in blood.
