Marriage? This must be a joke! Natalia Sokoloff has nerves of steel, but when David "Mac" MacAllister proposes marriage, she breaks into a cold sweat. A wife is Mac's best chance at adopting the son he fathered while on active duty in Iraq. And Natalia is his buddy. Besides, she owes him for saving her life during combat. So how can she refuse? Especially if this is temporary—they'd only need to play house until the adoption is final. Except even that's far too long and too intimate for Natalia. Because there are some things a girl doesn't want even her best friend to know!
