Coldhearted King: A Billionaire Workplace Romance (Empty Kingdom)

Why we recommend it

A billionaire workplace romance with a cold, controlling hero at its center. Expect office power imbalance, icy hostility melting into reluctant heat, and a heroine who refuses to be intimidated. The darkness here is emotional and psychological rather than violent. A good fit for readers who love grumpy, guarded tycoons, enemies-to-lovers friction across a boardroom, and the slow crack in a man who's forgotten how to feel anything but ambition.
