She rebuilt his family's empire. He let another woman take her name.

Isla Thorne gave up her own architecture firm eight years ago for one promise: equal weight, two names on every door. Now, three weeks before the reopening gala for the hundred-year-old hotel she restored with her own hands, her name is missing from the press kit, the credits, even the cornerstone plaque.

Then she finds the apartment. The perfume bottle. The wire transfer that doesn't match the invoice. Her husband hasn't just been unfaithful - he's been bleeding her own restoration budget to fund a second life with a woman she trained and trusted completely.

Every discovery peels back another layer of a fourteen-month betrayal built to survive an audit and a marriage in the same quiet motion. With a forensic-accountant best friend, a sister-in-law who's watched this family bury the truth before, and a steady structural engineer who never once made her feel small, Isla has one chance to make her name outlast every attempt to erase it - in front of four hundred witnesses who won't be able to look away.

This isn't a story about losing a marriage. It's about reclaiming a name. Read His Lost Wife today if you love billionaire betrayal romance with a heroine who fights back with proof, not tears.
