Sweet Revenge: Marrying My Ex's Ruthless Nemesis

Audie pushed her weight against the heavy brass handles of the Waldorf Astoria ballroom doors.

The thick wood gave way, releasing a wave of warm air thick with the scent of expensive perfume and roasted meats.

She slipped inside, instantly handing her damp trench coat to a waiting attendant at the cloakroom.

She smoothed her hands down the front of her tailored pencil skirt, making sure her professional attire wasn't too wrinkled from the subway ride.

Her eyes scanned the sprawling, opulent hall.

It was a sea of Ivy League elites, men in sharp tuxedos and women in flowing gowns, all mingling under the golden glow of the chandeliers.

She was looking for Ryder.

A waiter in a crisp white shirt walked past holding a silver tray.

Audie reached out and took a flute of champagne, the chilled crystal cooling her warm fingertips.

She pulled her phone from her clutch and checked the screen.

The text from Ryder, received exactly ten minutes ago, stared back at her: Waiting for you inside.

A sudden eruption of loud, enthusiastic applause drew her attention toward the center of the room.

Directly beneath the largest crystal chandelier, a crowd had formed.

Through a gap in the tailored shoulders of the guests, Audie spotted the familiar broad back of Ryder's custom navy blue suit.

Her fingers clamped around the stem of the champagne flute.

The skin over her knuckles stretched taut and turned a stark, bloodless white.

She dragged in a sharp breath, the air burning her throat.

It's just family networking, she told herself. Just standard Manhattan social politics.

But then Ryder tilted his head down.

He pressed his lips to Tatum's forehead in a slow, lingering kiss that radiated absolute devotion.

The air vanished from Audie's lungs.

Her brain short-circuited, flashing through a hundred tiny, easily explained absences over the last three months.

She pressed her thumb hard against her opposite wrist, grinding the bone to stop her hands from shaking.

She forced her legs to move, stepping closer to the center of the crowd.

The alumni surrounding them raised their glasses, their voices blending into a chorus of congratulations on the perfect union of two powerful families.

Audie stopped less than three feet away from them.

Tatum caught movement in her peripheral vision and turned.

When her eyes landed on Audie, a slow, malicious smile spread across
