The Sinclair Arrangement follows Eleanor Sinclair, the poised heiress of a New York business dynasty, forced into a strategic marriage with Adrian Varga—a calculating European investor whose charm hides secrets of his own. What begins as a cold alliance slowly evolves into something dangerously intimate, set against a backdrop of boardroom betrayals, buried family legacies, and a psychological surveillance plot stretching back a decade. As Eleanor fights to take control of her company and her own narrative, she must decide whether love is an asset—or the greatest liability of all.
