Lucas Ashford survived the accident.

His memories didn't.

Four years of his life are gone, leaving him to rebuild not only his career as CEO of Ashford Technologies, but also the marriage he can no longer remember. With Emma beside him, Lucas begins searching for answers about the mysterious investigation he abandoned before the crash.

What begins as a search for missing memories quickly becomes something far more dangerous.

Hidden records.

Altered reports.

Forged approvals.

Evidence that someone has been quietly manipulating the company's history for years.

As Lucas, Emma, and trusted investigator Daniel Mercer follow a trail of independently verified clues, they uncover a conspiracy built not around a single person?but around a system designed to survive anyone who tries to expose it.

Every discovery forces Lucas to ask a different question.

Not who changed the past.

But why it had to be changed.

While danger closes in and someone begins watching Emma, Lucas must decide whether he needs the memories he lost?or whether the man he has become is enough to finish the fight he started.

The Billionaire's Forgotten Heart is the emotionally charged second novel in the Forgotten Vows trilogy, blending billionaire romance, marriage, corporate suspense, and a gripping mystery about love, trust, and the courage to pursue the truth.
