Sam Kercher is a walking, talking, hulking specimen of a U.S. Marine.

So why is he toting a diaper bag instead of a sniper rifle?

When Sam's military pals call in a favor, they force him to face a new line of duty.

He's going undercover as a nanny for their newly divorced sister and her twin boys.

If Sam can assemble an M16 in his sleep, diaper duty should be easy, right?

But Operation Nanny isn't so simple.

Sheridan's sworn off overbearing military men, thanks to her dirtbag ex.

Sam's pledged to protect her from the guy without revealing he's a Marine.

It doesn't help that her brothers have ordered Sam not to touch her. Ever. Period.

Problem is, Sam's wanted Sheri for ages.

Even more now, with her lush new-mom curves and sexy mama-bear strength.

Sam's got his work cut out for him.

Protect the girl. Care for the babies. Hide his identity.

And keep his hands off Sheri.

But even the most disciplined Marine has his weakness.

And Sheri is one Sam's not sure he can resist.
