In the suffocating darkness of a penthouse, a powerful voice cuts through the silence. "I want to hear you break. I want to watch you suffer. I want you begging for mercy." The Gangster Billionaire's commands echo like thunder, each word a cage closing tighter. Luna—named for the moon she'll never see freely again—trembles at eighteen years old. Betrayed by her stepmother Cora's ruthless scheming, she's been traded like currency to a man who owns everything, including her now. "Please, I'm begging you," Luna whispers through tears, her voice barely audible. "Your father abandoned you. He sold you to me. No one wanted you." His cruelty cuts deeper than any blade. "No—my father loves me! He didn't sell me. Cora did this. My father was powerless against her!" Luna's protest dissolves into sobs, her truth drowning in accusation. "Silence." His roar shatters the air, and Luna's body convulses with fear at the sheer force of his dominance. What began as a nightmare of survival becomes something neither of them anticipated. Trapped in his world of danger and desire, Luna discovers that the man who bought her might be the only one willing to keep her—whatever the cost. In a game of possession and passion, can she survive the man who refuses to let her go?
