From romance author Kelly Collins comes Taming Mr. Wilder, a fake engagement, grumpy sunshine, forced proximity standalone novel.

Devney Sinclair thought she'd hit rock bottom when her grumpy billionaire boss proposed the most outrageous business deal of her career: pretend to be his fiancée to secure a multi-million-dollar investment. One fake engagement, a few public appearances, and she'd have enough money to finally quit her job as assistant to the most demanding CEO on Wall Street.

Ronan Wilder knows exactly what he wants—Andrew Beauchamp's investment and nothing more. He's built his empire on cold calculation, not messy emotions. But when his "family values" investor starts asking questions, Ronan needs a fiancée fast. His solution? The one woman who challenges him daily, argues with his impossible standards, and somehow makes his sterile office feel alive.

They're both convinced they can keep business and pleasure separate. But between stolen glances across boardrooms and heated moments behind closed doors, the line between performance and reality begins to blur.

Can a heartless CEO and his sunshine assistant pull off the deal of a lifetime without losing their hearts? Or will one impulsive moment of honesty destroy everything they've worked to build—including each other?

Some contracts are written in ink, others in stolen kisses and second chances.

A sharp, emotionally charged contemporary romance that delivers crackling tension, witty banter, and heartfelt payoff. Taming Mr. Wilder blends a classic fake engagement setup with modern workplace stakes, offering readers a grumpy billionaire hero, a resilient sunshine heroine, and a love story that proves some contracts are meant to be broken.
