The Billionaire's Secret Heir

Estelle Vance was the perfect wife - invisible, obedient, and madly in love with a man who stopped seeing her. The night she caught her billionaire husband Eric inches from kissing his first love, she didn't scream, didn't cry. She took the positive pregnancy test from the trash, left her wedding ring on the kitchen table, and vanished.
Five years later, the business world is terrified of an anonymous corporate shark dismantling companies with surgical precision. No one knows her name. No one has seen her face.
Until now.
Estelle walks into the biggest networking event of the year - stunning, ruthless, and accompanied by a six-year-old boy who looks exactly like Eric Vance.
Desperate for answers, Eric hires Samuel Wood, a dangerously charming ex-intelligence operative with a vendetta against the Vance family. Samuel's job is to uncover Estelle's secrets. Instead, he starts falling for her.
Now Estelle is trapped between the husband who swears he never betrayed her, a new ally who might be using her, and a mother-in-law willing to kill to keep her away.
She came back for revenge. She didn't plan on two men fighting for her heart.
