The envelope is white, unmarked, and sitting on my pillow when I return from the rehearsal dinner. I stare at it for three seconds before my hands move. Inside: a hotel key card and four printed screenshots from security camera footage. Time stamps from tonight. The penthouse suite at the Meridian—the hotel where half our wedding guests are staying. In the first image, Damien Cross—my fiancé, the man I'm supposed to marry in fourteen hours—has his hand on a woman's lower back as they step into an elevator. In the second, they're kissing against the hallway wall outside suite 4201. In the third, his jacket is on the floor. The fourth is taken from inside the room. I can see everything. The woman isn't a stranger. Victoria Chen. His "business associate." The one he's introduced at every charity gala for the past six months with that easy smile and the explanation that she's helping him expand into the Asian market. I should feel something. Rage, betrayal, the hot sting of tears. Instead, there's just cold clarity. I slip the key card into my clutch, leave my phone on the nightstand, and walk out of my childhood bedroom in my rehearsal dinner dress—cream silk, tasteful, the kind of thing a Lawson daughter wears. My heels click against marble as I pass my father's study. The door is open. He's on the phone, his voice low and urgent. He doesn't look up. The Meridian is four blocks away. I walk. --- The penthouse elevator requires the key card. I slide it through the reader and watch the button for the forty-second floor light up. My reflection stares back from the polished brass doors. Hair still perfect from the salon this morning. Makeup still flawless. I look exactly like the woman who's supposed to walk down the aisle tomorrow in a Vera Wang gown that cost more than most people's cars. The elevator chimes. The hallway is silent, plush carpet muffling my footsteps. Suite 4201 is at the end. I use the key card. The lock clicks green. I don't knock. The suite is dark except for the bedroom. Light spills from the half-open door. I hear her laugh—low, intimate, the kind of sound that doesn't belong in the same sentence as "business associate." I push the door open. They don't notice me at first. Damien is propped against the headboard, sheets pooled at his waist. Victoria is curled against his chest, her dark hair spilling across his shoulder. Two champagne flutes sit on the nightstand beside them. "I still think we should tell her," Victoria says. "Why?" Damien's voice is lazy, amused. "She'll find out eventually." "After the wedding?" "After I get what I need." He traces a finger down her bare arm. "Sienna's the respectable choice. You're the one I actually want. She gets the ceremony and the photographs. You get me." Victoria shifts, looking up at him. "And the legal marriage certificate?" "Goes to you, obviously. We'll have our private ceremony an hour after the cathedral show. Judge Morrison owes me a favor." He kisses her forehead. "Sienna will stand at the altar and say her vows while you sign the papers that actually matter. She'll be my wife in name. You'll be my wife in law." The champagne flute on the nightstand catches the light. I clear my throat. Damien's head snaps toward the door. For one satisfying second, I watch his expression fracture—shock, then calculation, then something that almost looks like annoyance. "Sienna." He doesn't move to cover himself. Doesn't scramble for an explanation. "I wasn't expecting you until tomorrow." Victoria pulls the sheet higher but doesn't leave. She watches me with dark, calm eyes. "Clearly." I step into the room. My voice comes out steady. "How long?" "Does it matter?" "Humor me." Damien shrugs. "Eight months. Since the Singapore trip." The Singapore trip. The one where I stayed home with food poisoning while he closed the deal that saved his company. I nod slowly. "And this?" I gesture between them. "This is what, exactly?" "Practical." He leans back against the headboard like we're discussing stock portfolios. "You're Harrison Lawson's daughter. Perfect breeding, perfect connections, perfect face for the society pages. Victoria is—" "What you actually want," I finish. "Yes." The word sits in the air between us. I should scream. Throw something. Collapse into the kind of dramatic scene that would give the hotel's night staff something to whisper about for months. Instead, I twist the engagement ring off my finger—three carats, princess cut, chosen by his mother—and set it on the nightstand beside the champagne. "Sienna." Damien's voice sharpens. "Don't be stupid. We can still—" "Enjoy your evening." I turn and walk out. My hands don't shake until I reach the elevator. The doors close and I'm alone with my reflection again, and that's when I feel it—not heartbreak, but something colder. The specific weight of a future dissolving. The cathedral. The dress. The five-tier cake. Three hundred guests. My father's proud smile. The elevator descends. I don't know where I'm going. Home means facing my father, and I can't look at him right now without thinking about how much money he's spent on tomorrow. Can't think about tomorrow at all without my throat closing. The lobby is empty except for the night clerk. I push through the glass doors into the midnight air. A black town car idles at the curb. As I step onto the sidewalk, the rear door opens. Inside, a man sits in shadow. Dark suit. Dark hair. The kind of presence that makes the air feel heavier. "Sienna Lawson." His voice is low, controlled. "Get in." I should walk away. Should run. Instead, I meet his eyes—ice blue, sharp enough to cut—and recognize him. Rhys Maddox. The billionaire Damien destroyed five years ago. The one who lost everything when Damien's hostile takeover gutted his company and left him publicly humiliated. He leans forward into the light. "I'll be your groom."
