Hannah George has had a rough three months. Her mom died, her dad is an emotional zombie, and her high school sweetheart broke up with her. To add to her heartbreak, she uncovers a scandalous fact about her dad: he left a woman at the altar over twenty-five years ago and never apologized. Wanting to live up to her mother's mantra of living without regrets, Hannah vows to track down the woman her dad left at the altar, so he can finally apologize.
Will Whitmore, aspiring author, city slicker, and annoyingly attractive jerk couldn't be more different from Hannah's small town, southern upbringing, but when he offers his help in finding the woman her father left at the altar, they are stuck together all summer long on a cross-country road trip.
As the summer progresses, Hannah finds that sometimes love is found in somebody who is different from you in every conceivable way. All summers and road trips come to an end, though, leaving Hannah to wonder if love is worth the risk.
