The billionaire's vow.

The letter arrived on a Thursday. Ava stared at the cream-colored envelope in her hands. Her name was written across the front in elegant, threatening script. No return address. No explanation. Just her name. She knew who it was from. Alexander King. The billionaire. The recluse. The man who owned half the city and destroyed anyone who crossed him. Her hands shook as she opened the envelope. Inside was a single sheet of paper. Thick. Expensive. The words were typed. *"Miss Ava Bennett,* *Your father's company is days from bankruptcy. I can save it. In exchange, you will marry me. One year. Strict contract. No feelings. Divorce at the end.* *You have twenty-four hours to decide.* *If you agree, come to my penthouse tomorrow at 8 PM.* *Do not be late.* *— Alexander King"* Ava read the letter three times. Marry him? She had never met him. Never spoken to him. She had only seen his picture in business magazines. Cold eyes. Sharp jaw. A face that never smiled. She wanted to throw the letter away. Burn it. Pretend she had never seen it. But her father's company was everything. Her father had built it from nothing. Her mother had died building it. If the company fell, her father would fall too. She had watched him struggle for years. Watched the light fade from his eyes. She could not let him lose everything. --- The next evening, Ava stood outside Alexander King's penthouse. The building was the tallest in the city. Glass and steel. Lights that seemed to touch the clouds. She wore her best dress. Black. Simple. The only expensive thing she owned. A man in a black suit opened the door. "Miss Bennett. Mr. King is expecting you." She followed him inside. The penthouse was enormous. Floor-to-ceiling windows. A view of the entire city. Furniture that cost more than her father's house. And in the center of the room, standing by the window, was Alexander King. He was taller than she expected. Broader. His suit was black. His hair was dark. His eyes were gray. Cold. Unreadable. "You came," he said. "You gave me no choice." "There is always a choice." Ava stepped closer. Her heart was pounding. But she refused to let him see her fear. "Why me?" Alexander turned to face her fully. His gaze traveled over her face. Her dress. Her hands. "Because you are desperate. Desperate people are predictable." "I'm not desperate. I'm loyal." "Same thing." "It's not." He walked to a table. Poured himself a drink. Did not offer her one. "Your father's company is worth nothing. The debt is crushing. The banks will take everything in days." "I know." "I can write a check and save it all." "And in exchange, I marry you." "For one year. Then divorce. You walk away with enough money to never work again." Ava's hands clenched. "Why do you need a wife?" Alexander's jaw tightened. "That is not your concern." "It is if I'm marrying you." He stared at her for a long moment. Then he set down his glass. "A business deal requires a stable image. A wife helps that image. You will attend events. Smile for cameras. Say the right things." "A trophy wife." "An arrangement." Ava wanted to leave. Wanted to run. But she thought of her father. His tired eyes. His shaking hands. "I'll do it." Alexander's expression did not change. "Good." --- He walked to his desk. Pulled out a contract. Thick. Pages long. "Read it. Sign it. Then we are married." "Just like that?" "Just like that." Ava sat down. Read every page. The terms were strict. She would live in his penthouse. She would attend all events. She would not see other men. She would not speak to the press. She would not fall in love with him. One year. Then divorce. She would receive ten million dollars. Ten million dollars. Her father's company would be saved. Her father would be safe. She would never have to worry about money again. She picked up the pen. Signed her name. Alexander signed beneath hers. "You are now Mrs. King." Ava felt the weight of the words. Mrs. King. Married to a stranger. A cold, ruthless stranger. "We need to discuss ground rules," he said. Ava stood. "Rule one. You do not tell me what to do." Alexander's eyes narrowed. "Excuse me?" "You heard me. I signed your contract. I will attend your events. I will smile for your cameras. But I am not your property." "You are my wife." "I am your partner. There is a difference." Alexander stepped closer. His gray eyes were intense. "You are brave. Or stupid. I haven't decided which." "Does it matter?" "No." He walked to the window. Stared at the city below. "Rule two. You do not enter my bedroom. You do not touch my things. You do not ask about my past." "Fine." "Rule three. Do not fall in love with me." Ava laughed. It was a bitter sound. "Trust me, Mr. King. That will not be a problem." He turned to look at her. Something flickered in his eyes. Something she could not name. "We shall see." --- The doorbell rang. Alexander's assistant entered. A young woman with glasses and a clipboard. "This is Claire," Alexander said. "She will show you to your room." Ava nodded. Followed Claire down a long hallway. "Your room is here," Claire said. "Mr. King's room is at the other end of the hall. He values his privacy." "Good. I value mine." Claire almost smiled. "You're different." "Different how?" "Most people are afraid of him. You're not." Ava looked at the closed door at the end of the hall. Alexander King's door. "I'm terrified," she said. "I just don't show it." Claire nodded. "You'll fit in just fine." --- Ava closed her bedroom door. Leaned against it. She was married. To a stranger. A cold, ruthless billionaire. She had signed a contract. Agreed to one year. Agreed to not fall in love. She looked at the city lights through her window. "What have I done?" she whispered. The city did not answer. Across the hall, in his own room, Alexander King stood by his window. He was thinking about his new wife. Her fierce eyes. Her steady voice. The way she had refused to back down. "You're different," he whispered. He did not know if that was good or bad. But he was about to find out.
