A love built on betrayal, vengeance, and an undeniable hunger for control. Madelaine never saw it coming. Used as a pawn in her father’s cruel games, she’d spent her life building walls to keep her heart safe. But everything changes when she crosses paths with Paulo Ruffino. Cold, calculating, and driven by a thirst for revenge, he has no intention of asking for her trust—but he offers her protection . To Paulo, Madelaine is nothing more than a tool in his ruthless plan to take down the man who destroyed him. He doesn’t give her a choice. She’s his leverage, his prize to claim, and a pawn in the dangerous world of power and manipulation he controls. But as he spends more time with her, his hard, calculated exterior begins to crack. Her strength, her vulnerability, and the undeniable chemistry between them make his cold emotions feel strangely out of place. The more he gets to know her, the more he realizes that using her might not be as easy as he once thought. As Paulo’s plans begin to falter, the tenderness he’s fought so hard to suppress starts to rise, leaving him torn between his thirst for vengeance and the unexpected desire to protect the woman he’s tried to control.
