Marcus's phone lights up on the nightstand at 2 AM, and I know exactly who it is before he even reaches for it. "Elena," he breathes into the receiver, and just like that, I'm invisible again. I lie perfectly still in our bed—his bed, really—watching the shadows play across the ceiling while my husband of eleven months whispers sweet reassurances to the woman he actually loves. The woman he's always loved. The woman who left him three years ago to marry a tech mogul in Singapore, breaking his heart so thoroughly that he needed a replacement wife to prove he'd moved on. That's me. The replacement. The consolation prize. The girl from nowhere who should be grateful Marcus Thorne even glanced in her direction. "Of course I remember," he murmurs, turning away from me like I'm just another piece of furniture. "Venice. The suite overlooking the canal. Baby, I've never forgotten." My nails bite into my palms beneath the silk sheets his mother picked out. Everything in this house was chosen by someone else. The cream-colored linens. The abstract art in the hallways. Even me, in a way—selected from the catalog of suitable candidates his assistant had compiled after Elena's wedding announcement went viral. *Must be presentable, undemanding, and grateful for the opportunity.* I checked all the boxes. He ends the call after ten minutes that feel like hours. Doesn't explain. Doesn't apologize. Just sets the phone down and rolls over, his back a wall between us. "Marcus," I whisper. Nothing. He's already asleep, or pretending to be. Same difference. I slip out of bed at dawn while he's still snoring softly, that peaceful expression on his face that he never wears when he's awake and looking at me. In the kitchen, I start his coffee exactly how he likes it—two sugars, splash of cream, heated to 180 degrees because anything hotter irritates his acid reflux. I've memorized every preference, every dietary restriction, every small need that makes his life run smoothly. That's my job, after all. I'm paid $3,000 a month to be Mrs. Marcus Thorne. To manage his household staff. To smile at his business dinners. To visit his grandmother at the care facility every Thursday because he's too busy. To exist in the margins of his life without ever demanding he actually see me. His mother arrives at eight-thirty, letting herself in with her own key. "Isla, darling." Catherine Thorne air-kisses near my cheek, her Chanel perfume overwhelming the scent of the frittata I'm plating. "Is Marcus awake? We need to discuss the Foundation gala seating arrangements." "I'll get him," I murmur, but she's already sweeping past me toward the stairs, calling his name. I don't exist to her either. I'm just the girl who opened the door. By nine, I'm in the car heading to my real job—the one Marcus knows nothing about. He thinks I spend my days shopping or getting spa treatments or whatever it is trophy wives do with their empty hours. He's never asked. In eleven months of marriage, he's never once said, "How was your day?" or "What did you do while I was gone?" If he had, I'd have to lie. And I'm so tired of lying. "Dr. Winters." My lead engineer, James, greets me the moment I step into the lab. "The latest iteration is ready for testing. The compression algorithm is performing 40% better than projected." I shed Isla Thorne like a coat, stepping into the skin of Dr. Isla Winters, MIT graduate, quantum computing specialist, and lead architect of Project Meridian—the encryption technology that's about to revolutionize data security and, incidentally, make Marcus's flagship cybersecurity division completely obsolete. He has no idea. No idea that the mousy wife who makes his coffee and laughs at his colleagues' terrible jokes holds three patents and a PhD. No idea that his biggest business rival, Victor Chen, has been courting me for six months, offering everything from unlimited research funding to a corner office in Shanghai. No idea that the woman he ignores is about to destroy him. "Run the tests," I tell James, pulling on my lab coat. "I want full diagnostics by end of day." My phone buzzes. Marcus: *Forgot to mention, Elena's back in town. Having dinner with her tonight. Don't wait up.* No pretense. No excuse. Just a simple notification that he's choosing her, the way he always does, the way he always will. I stare at the message until the words blur. Then I open my email and pull up Victor's latest message, the one I've been avoiding for three weeks: *The Shanghai Tech Conference is next month. Come as my guest. It's time the world sees what you've built.* My finger hovers over the reply button. Marcus thinks I'm nothing. A convenient placeholder. A warm body to fill the space Elena left behind. He's about to learn exactly how wrong he is. I type three words: *I'll be there.* And just like that, everything changes.
