From the author of PS, I LOVE YOU, a simultaneously funny and tender novel about what happens when two people who are destined to be together can never seem to get it right.

Rosie and Alex are destined for one another, and everyone but them seems to realize it. Rosie's best friend since childhood, Alex never did live down the fact that he didn't invite her to his all-boys 10th birthday party. But that wasn't a mistake he'd repeat, and they had been inseparable after that ....until the day Alex got the news that his family was moving to Boston. At seventeen, Rosie and Alex are starting to see each other differently, and the move separates them just when their relationship seems as if it will finally turn romantic. Devastated, the two make plans for Rosie to apply to colleges in the U.S. Rosie gets into Boston University, Alex gets into Harvard, and everything is falling into place, when on the eve of her departure, Rosie gets news that will change their lives forever: Rosie is pregnant. And the father is not Alex.

Her dreams for college, Alex, and a glamorous career are dashed against harsh reality, and Rosie stays in Dublin to become a single mother, while Alex pursues a medical career. As the years pass, the two continue to interact, but can't seem to find each other at the right time. But destiny is a funny thing, and in this novel, structured as a series of clever e-mails, letters, notes, and a trail of missed opportunities, Alex and Rosie will find out that fate isn't done with them yet. From the hugely talented author of PS, I LOVE YOU, this is a funny, romantic, surprising novel that is impossible to put down.
