"I didn't—" He crossed the room in four strides. His hand closed in my hair and drove me to my knees before i could breathe. "You're not going home," Caleb Wren said quietly. "Your sister's wedding is in four days. You look exactly like her." His eyes moved over me, cold and final. "You're going to take her place. Consider it what you owe."

I had stopped pretending the night Sebastian sailed past our bedroom door for the third time and didn’t look back. I had married him to keep my father’s company intact. Out of my father's desperation. The vows were for the cameras and the board, everything else was ledger entries and quiet compromises. He chased his affairs in public while I held the facade. He saw my composure and called it martyrdom. He never figured out that my calm was armor, not devotion. Then Samantha came home, twenty-three, luminous, curious, the kind of warmth that made places in me I’d kept cordoned off ache. She drifted into my life with easy laughter and careless questions. A sister-in-law, that became my obsession. We started with late-night talks, her voice soft in an empty house, her hand brushing mine while we pretended we were discussing nothing at all. Those small touches stopped being accidental, but deliberate. While Sebastian was busy elsewhere, I took his sister. Not to win anything on a balance sheet, not to score a victory, but to finally have the means to protect who I am, and who I love.

When the scandal around Sebastian crescendoed, I didn’t hide behind the marriage or the name. I stepped into the light, shoulder to shoulder with her, exposed and fierce. I traded anonymity for that, truth wrapped in possession, and I, Mikayla Stonefield, would have done it again.
