Blurb "Sign the papers, Celeste." I wiped the blood from my nose, my hands trembling as I handed my husband the contract I had worked tirelessly to finalize for him. But instead of gratitude, he shoved divorce papers in my face. And beside him, smirking in triumph, was the woman he had replaced me with—the daughter of his boss. Five years of sacrifice, of love, of loyalty… all reduced to nothing. Ethan Carter had used me, discarded me, and now he was climbing higher on the back of another woman. I thought that was the end of my story. Until he appeared. Damien Sinclair—the youngest billionaire in the country, ruthless in business, feared by his enemies, and a man who never gave without taking something in return. And he wanted me. Overnight, I went from the forgotten ex-wife to the envy of high society, the woman draped in luxury, held in the arms of a man who commanded the world. But Damien’s interest in me wasn’t coincidence. He knew my past. He knew my pain. And when he whispered my childhood nickname in his sleep, I realized… he knew me. Now, I must uncover the truth before I lose myself in the passion, the power, and the dangerous game I never saw coming. Because in Damien’s world, love is just another negotiation—and I might be the one paying the ultimate price.

Betrayed. Broken. Stripped of everything she once called hers. Elysia Sinclair thought she had already lost it all—until she lost the one thing that truly mattered. Her baby. Left bleeding and abandoned in a cold hospital room, she swore revenge. But what could a woman with nothing do against the man who destroyed her? Enter Adrian Blackwood. Ruthless, calculating, and as dangerous as they come. He doesn’t do charity. He doesn’t do kindness. But when he looks at Elysia, he sees something more—something raw, something familiar. "Sign these papers, leave him, and marry me," he says, his voice a dark promise. "I'll help you get your revenge." It’s a deal with the devil himself, but Elysia is too shattered to refuse. One signature, and she goes from the discarded ex-wife of a billionaire to the new bride of a man even more powerful. But Adrian didn’t just want a wife. He wanted her.

One thing is certain: when you strike a deal with the devil, there’s no turning back.

Emery Sinclair had spent years perfecting the art of being the perfect wife. The devoted, loyal, and elegant Mrs. Sinclair. Even when whispers of her husband's infidelity trailed after her like a ghost, she held her head high, convinced that love—her love—was enough to fix the cracks in her marriage. But the moment she walks into that hotel suite and finds her husband entangled with another woman, something inside her shatters. She doesn’t cry. She doesn’t scream. Instead, she walks away, her heart numb, her mind spinning. The life she built is over. The man she sacrificed everything for never deserved her. Then comes Killian Wolfe. Cold, calculating, and ruthlessly powerful, Killian is everything her husband is not. And he is done watching from the sidelines. For years, he’s kept his distance, biting his tongue as his foolish stepbrother squandered the one good thing in his life. But now? Now, Killian doesn’t hold back. He steps in—offering her a way out, a place to stay, and, most dangerously, a deal she never saw coming. "Let me take care of you," he tells her, his voice a low, commanding whisper. She should say no. She should run. Because nothing about Killian Wolfe comes without a cost. But the way he looks at her—like she’s something precious, something worth ruining kingdoms for—makes her wonder if, just this once, she should let herself be wanted. The game changes in a single night. A kiss turns into something more, and before she knows it, she’s tangled in his sheets, in his world, and in his control. But Killian doesn't just want her in his bed. He wants everything—her body, her mind, her soul. And most terrifying of all? He wants her heart.
