My Fiancé and the Sister I Raised Replaced Me With an Heiress

Chapter 1

The crystal vial on the marble countertop caught the morning light, casting fractured rainbows across the kitchen island. Clara Vance did not look at the rainbows. Her eyes were fixed on her own hands—the thick, puckered tissue that mapped the backs of her knuckles, the shiny, pale scars that crept up her wrists and vanished beneath the cuffs of her modest silk blouse.

Ten years ago, she had plunged those hands into the roaring flames of their childhood home to pull her little sister out of the inferno. The doctors had told her she would never have full mobility again. They were wrong. She had forced her fingers to work, to hold pipettes and blend essential oils, to build a billion-dollar fragrance empire from the shadows.

Today was Mia’s nineteenth birthday. For six months, Clara had worked in secret, blending and re-blending, discarding hundreds of test strips to create the ultimate bespoke fragrance for her sister. She called it *L’Aube*—The Dawn. It was a masterpiece of white iris, crushed green leaves, and a heart of rare Madagascar vanilla. It was a scent meant for a girl stepping into womanhood, a girl Clara had raised with her own blood, sweat, and ruined skin.

"Clara, tell me the caterers are setting up the mimosa bar on the terrace."

Clara nudged the crystal vial across the marble.

Mia stopped texting on her phone and blinked at the bottle. The eager light in her eyes instantly dimmed. "Perfume?" she asked, her tone flattening. "You’re giving me perfume? Clara, I live with the ghost-creator of Thorne Empire. Our bathrooms are literally overflowing with perfume."

"Not this one," Clara said gently. "This is custom. I’ve been working on it for half a year. It’s formulated to your exact skin chemistry. It’s a completely unique scent, Mia. Nobody else in the world will ever have it."

Mia picked up the vial, her perfectly manicured nails tapping against the glass. She didn't open it. She didn't smell it. "It’s… in a plain bottle," she noted, her lip curling slightly. "No label. No gold filigree. It looks like a lab sample."

"The beauty is in the formula," Clara explained, fighting the tight sensation in her chest. "The top note is white iris. It represents—"

"Yeah, that’s great, Clara, really," Mia interrupted, setting the bottle back down with a sharp clink. "It’s just… well, I thought Julian was going to talk to you. I told him I needed a car. A
