When my fiancé chose my sister over me, I lost everything—my future, my dignity, my family's respect. They expected me to fade away quietly, to accept the betrayal as my burden to bear. Axel O'Brien didn't offer sympathy. The ruthless billionaire offered something far more valuable: a partnership forged in darker intentions. His proposition was direct: marry him, align yourself with his power, and watch those who destroyed you crumble in return. I should have recognized the danger. Should have questioned why he'd help a stranger burn down her own family. But desperation makes poor choices seem reasonable. The plan was flawless—become Axel's devoted wife, cement his place in their world, and exact revenge together. What could be simpler than that? Everything, as it turns out. Axel plays the role of an attentive husband too convincingly. His touch lingers too long. His protection feels too genuine. And somewhere between our calculated performances and his devastating presence, I've developed feelings that have no place in a marriage built on vengeance. Worse still is the growing suspicion that I was never his partner in this game—I was always his weapon. That Axel had meticulously crafted every moment, waiting for me to fall. Now I'm caught between two truths: the revenge I came for and the man I'm becoming dangerously close to. And I have to decide which betrayal cuts deeper—his calculated deception or my own reckless heart.
