When a reclusive AI ethicist is named the sole heir to a tech billionaire's empire, she expects chaos—but not a legally binding engagement to his cold, infuriating nephew. Bound by a contract neither of them wrote, Mira Elan and Lucien Veltier must pretend to be in love for one year to claim the inheritance. But the deeper they fall into Elijah Veltier's maze of legal riddles, emotional AI, and corporate deception, the more they realize: they're not just playing a part—they're being played.

The Widow's Heir is a slow-burn romantic thriller layered with intelligence, tension, and emotional intrigue. Perfect for fans of arranged-marriage power games, elite family secrets, and heroines who refuse to be programmed.
