My Stepsister Stole My Groom

She stole my wedding. I stole her future.
On the morning of my wedding, I caught my fiancé Kellan tangled in the sheets with my stepsister. The betrayal should have shattered me. Instead, it lit a fire in my veins.
So I did what any woman scorned would do.
I pointed to the most dangerous man in the room-Drexon Moreaux, Kellan's ruthless billionaire uncle-and declared, "Him. I'll marry him instead."
Drexon could have laughed in my face. The Moreaux empire's heir apparent, a man forged in boardroom battles and whispered about in elite circles, had no reason to entertain my reckless demand.
But he said, "I do."
Now, my stepsister's smug smile is crumbling. My ex-fiancé is forced to call me Auntie. And Drexon? He watches me with dark, calculating eyes, as if I'm a puzzle he's determined to solve.
This marriage was supposed to be my revenge. But with every lingering touch and midnight confession, Drexon is turning it into something far more dangerous-something that feels like love.
Too bad the Moreaux family doesn't believe in happy endings.
