Upton Sinclair Novels

I never expected my boss to blackmail me into marriage. Ethan Sinclair the cold, calculating billionaire who never cracks a smile holds a secret over my head, forcing me into a fake marriage to secure his family’s inheritance. I hate him for it, but I need the money to save my brother’s life. The rules are simple: play the devoted wife for a year, follow his lead in public, and stay out of his way behind closed doors. But as sparks fly and buried secrets unravel, I realize Ethan isn’t just ruthless, he’s hiding something even more dangerous. The closer I get, the harder it becomes to remember this is all just a contract. Because falling for the devil was never part of the deal.

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.
