The champagne glass shatters against the marble floor, and for one perfect second, the entire ballroom goes silent. I stare at my mother—Margaret Hargrove, elegant in midnight blue silk—as she holds out her hand. Not to help me. To take. "The necklace, Isla." My fingers move to my throat automatically, finding the sapphire that's been there since I was sixteen. My grandmother's necklace. The one thing in this house that was supposed to be mine. "Mom, I don't—" "Now." Around us, two hundred guests pretend not to watch. The orchestra has stopped playing. The servers have frozen mid-step. This is my engagement party—mine and Adrian's—and my mother just made me drop a glass in front of everyone who matters in Manhattan society. I'm twenty-eight years old. I'm the COO of Hargrove Industries. I just closed a deal that saved fourteen jobs and brought in three million dollars. And I'm unlocking my grandmother's necklace because my mother told me to. The sapphire drops into her palm. She doesn't even look at it. She's looking past me, toward the entrance, where the real show is about to begin. "Go upstairs and change," she says. "Your father's study. There's something on his desk for you." "Change? Mom, this is my engagement dress. I designed it myself—" "That's why you need to change." Her smile is the kind that makes board members resign. "Celeste is wearing it better." The words don't make sense. Then I turn, and I see her. Celeste Hargrove—my half-sister, the one who appeared six months ago with a DNA test and a trust fund—is descending the grand staircase in my dress. Not one like it. Mine. The champagne silk with the hand-beaded bodice, the one I spent three months designing with a private atelier. The one that was hanging in my closet this morning. She reaches the bottom step, and my mother crosses the ballroom to clasp the sapphire around her neck. The necklace I've worn for twelve years. The one my grandmother gave me on her deathbed. On Celeste's throat, it catches the light differently. Or maybe that's just me, seeing everything differently now. "Isla." My father's voice, quiet beside me. Richard Hargrove, silver-haired and still commanding at sixty-three. "Go upstairs." "Dad, what's happening?" "We'll discuss it after. Go." I go. Because that's what I do. I climb the stairs while my half-sister greets my guests in my dress. I walk the hallway lined with family portraits—all of them mine, none of them hers yet—and I push open the door to my father's study. The dress on his desk is simple. Navy blue, high-necked, long-sleeved. The kind of thing you wear to a funeral, not an engagement party. There's a note on top, in my mother's handwriting: *This is more appropriate.* I change because I don't know what else to do. The silk puddles at my feet—I'd been wearing the most beautiful thing I'd ever owned, and now I'm stepping into something that makes me look like a governess. When I return to the ballroom, Adrian still hasn't arrived. My fiancé, late to our own engagement party. I've been checking my phone all night. Nothing. Celeste is holding court near the champagne tower, laughing with women who've known me since I was born. My mother stands beside her like a proud general. My father is across the room, deep in conversation with the Winthropes. I'm alone in the middle of my own engagement party, wearing someone else's idea of who I should be. Then the doors open, and Adrian walks in. Adrian Castellane. Thirty-four, dark-haired, devastating in a custom tuxedo. The man who proposed to me three months ago on a rooftop in Paris. The man who told me I was the only woman he'd ever loved. He scans the room, and his eyes land on Celeste. He crosses to her first. Not to me. To her. I watch him lift her hand and kiss it. I watch him smile at her the way he smiled at me in Paris. I watch my mother beam. Then he says something that carries across the ballroom, clear as a bell: "Finally. The daughter who deserves celebrating." The room tilts. I reach for the nearest table, but there's nothing there. Adrian's eyes find mine across the crowd. There's no surprise in them. No guilt. He's known I was standing here the whole time. "Isla." My father's hand on my elbow, steering me toward the terrace. "We need to talk." "Dad, what is he—" "The engagement was arranged." His voice is clinical. Businessman-flat. "Adrian approached me four months ago about a merger between Castellane Holdings and Hargrove Industries. The marriage was part of the agreement." Four months ago. Before Paris. Before the proposal. "He asked me to marry him." "He asked to marry a Hargrove." My father won't look at me. "When Celeste's DNA results came back and we confirmed she was my biological daughter, Adrian requested a substitution. He wanted to marry the legitimate heir." The words land like physical blows. Substitution. Legitimate. "I'm your daughter. I've run your company for six years. I built the acquisition division from nothing. I—" "Celeste is my blood." He says it simply, like it's a fact of nature. "The engagement was always meant to be hers. The ring on your finger was temporary. A placeholder until she was ready." I look down at my hand. The diamond catches the light, cold and brilliant. "Adrian's known for months," my father continues. "We all have. Tonight was supposed to be the transition. Clean, public, final." He finally meets my eyes. "I'm sorry you're upset, but this is what's best for the family." Inside, through the terrace doors, Adrian is dancing with Celeste. My mother is watching them like she's watching her daughter's wedding. And I'm standing here in a borrowed dress, wearing another woman's ring, realizing I was never the bride at all. I was just the rehearsal.
