Baseball player. Single dad. Hot mess. No woman has ever tamed him… until now.

Everyone knows Ryan Riggs—everyone who follows minor league baseball, that is. He's the player with the hair-trigger temper, the bad shoulder, and the smoking hot looks. He's also a single dad in need of a nanny—which makes him my new boss.

Simple. Except for one thing: We had a one-night stand five years ago.

We're trying to be professional. But it was one of the best nights of my life, and the more I work with him, the more I'm thinking about a repeat.

He's battling his demons, and I might be the only one who can help him win.

He's impossible.

He's unforgettable.

He's unwinnable.

Looks like I have my work cut out for me.
