Dump My Heartless Husband and Son: Billionaire's Regret Second Chance Romance

My son removed my face from the wedding photo and replaced it with his father's mistress.
My son thanked her for "her contributions to the family." Killian sat in the head seat, smiling gently.
Twenty years ago, I was a high-born heiress who married down for love. I sacrificed my status, my youth, and my family’s money to build Frost Corporation from scratch for a broke nobody.
And my reward? Being treated like an unpaid maid in my own home.
So I took my daughter's hand, walked out of that room, and slammed the divorce papers in front of him.
Killian thought I’d starve. He thought I was powerless without him.
He forgot—I built Frost Corporation for him single-handedly.
Now, everything bearing my name, I'm taking back, one by one.
By the time he realizes what he's lost, I'll already be out of his reach.
