Grace O'Leary has a secret. She keeps it locked away and experience has taught her to guard it carefully by avoiding long-term relationships. She keeps men at a distance, never letting anyone too close, not even when they're charming and handsome and everything she's ever wanted. Like Joe Mura. Joe's parents had a disastrous marriage, leading him to think of "commitment" as a four-letter-word. But then he meets Grace. She's smart, witty, sassy and beautiful, and he has never been drawn to anyone like he is drawn to her. Suddenly playing the field doesn't seem so appealing to Joe. But there's one problem: Grace has made it clear she's not interested in a serious relationship. Over more than a year and across three states, the two find themselves repeatedly in each other's orbit and eventually entangled in a passionate affair. Everything seems great until Grace's secret is revealed. Can Joe break down the walls Grace has put up around herself? Or will her secret create a barrier that is too much for their love to overcome?
