About Mr. Ruthless

An impossible bet. An undeniable attraction.

Adrianna Baker has poured everything into the Williamson Foundation—her time, her energy, her heart. But when Elijah Samson steps in as her new boss, all he sees is a problem to fix. Cold, calculating, and convinced she’s part of the corruption he’s trying to erase, Elijah makes it clear he wants her gone.

Adrianna isn’t going down without a fight. When he offers her a bet that could secure her dream position, she takes the challenge—determined to prove she’s more than just an assistant with a past. But the more time they spend together, the more the lines blur between enemies and something far more dangerous.

Elijah thought bringing Adrianna down would be easy. Instead, she’s burrowing under his skin in ways he never expected. The deeper he digs into her past, the harder it becomes to reconcile the woman he thought he knew with the one he can’t seem to resist.

The bet was supposed to settle things between them. Instead, it might just change everything.
