The Heiress's Vengeance: You Chose the Wrong Sister

Chapter 1

The crystal chandeliers of the Grand Plaza Hotel cast a brilliant, fractured light over the ballroom, illuminating the elite of the city's business world. Waiters in crisp white tuxedos wove through the crowd, balancing trays of vintage champagne, while a string quartet played a soft, classical rendition of a modern pop song in the corner.

It was the most important night of Sienna Vance’s life.

Standing near the edge of the dance floor, Sienna adjusted the discreet earpiece tucked behind her curled dark hair. Even at her own engagement gala, she couldn’t stop working.

"Sienna," a frantic voice buzzed in her ear. "The catering staff is short on the caviar blinis for the VIP tables."

Sienna pressed a finger to her ear, her eyes scanning the room. "Pull the reserves from the secondary kitchen, Marcus. And make sure the investors from the Sterling group get served first. Liam needs them happy tonight."

"Copy that. You’re a lifesaver, Sienna."

"Just doing my job," she murmured, letting her hand drop.

She took a deep breath, smoothing the fabric of her understated, navy-blue evening gown. It wasn't the most extravagant dress in the room—not by a long shot—but it was elegant. She had spent the last five years of her life pouring every ounce of her energy, her savings, and her operational genius into building Thorne Developments from a struggling startup into a respectable mid-tier firm.

"Everything is running perfectly, Liam," Sienna said, taking the glass. "The Sterling investors are in a fantastic mood. The quarterly projections are loaded onto the prompter for your speech."

Liam’s smile faltered for a fraction of a second, his eyes darting toward the VIP section before returning to her. "You always think about the business, Sienna. Take a breath. Tonight is about celebrating."

"I am celebrating," she replied, stepping closer and lowering her voice. "I’ve been waiting for this night for five years. We built this together, Liam. We finally made it."

He took a sip of his champagne, his Adam's apple bobbing. "Right. Together. Listen, Sienna... about the speech tonight."

"Is the pacing off? I can tell the tech team to slow down the prompter—"

"No, the prompter is fine," Liam interrupted, his voice tighter than usual. He reached out, his thumb brushing
