Tempting Mr. Callahan: One Night. One Rule. One Lie. (Billionaires’ Games)

Revised edition — professionally proofread (2026)


A CEO to die for. A secret that could shatter everything. And me—the assistant who can’t afford to lose him twice.

Six years after our one forbidden night, I’m still by Dante Callahan’s side—playing the role of the perfect, ice-cold professional. To the world, he is the untouchable titan of industry. But beneath the bespoke suits and calculated arrogance lies the man who haunts my every waking thought. Dante is my boss, my biggest mistake... and my ultimate temptation.

The stakes change when he sets his sights on a family business that means more to me than he could ever guess. Suddenly, I’m caught in a lethal crossfire between loyalty and desire. Every step closer to him is a step closer to the edge.

This time, if I fall, I won’t just lose my career. I’ll lose myself.


Tempting Mr. Callahan kicks off the Secret Games series, a part of the greater Billionaire Games universe—centered on the powerful men of the Dominion Society and the women who bring them to their knees.

Each book in this series is a standalone story, yet recurring characters weave them into a gripping, interconnected world. Perfect for fans of boss, CEO, billionaire, secret baby, pregnancy, surprise daddy, and enemies-to-lovers romances.
