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.
