Millionaire ad executive Landon Downey has a policy: no romantic relationships allowed. So when he's saddled with his six-year-old nephew for a week, he doesn't think twice about asking a female friend to act as live-in nanny. What he doesn't expect is the palpable attraction to the woman he hasn't seen in sixteen years. And not only does she like him back, she suggests they work their way down a list of extracurricular activities in the bedroom. How can he resist?

Kimber Reynolds knows what she's doing. Sort of. Tired of every failed attempt to turn her past relationships into her own happily-ever-afters, she's determined to prove once and for all that she can love em and leave em with the best of them. All she has to do is keep her heart out of the agreement she's made with the man she's crushed on for a decade and a half. No problem.

Their string-free arrangement turns downright stringy when Landon starts to feel more for the redhead than good old fashioned lust, and Kimber has a scare involving a plastic stick and one-or-more blue lines. With the pressure mounting and their hearts involved, will these two be able to keep their original promise and walk away from one another?
