One Day by David Nicholls (2009)

We follow Emma and Dexter through twenty years on one day each year. It starts with their graduation day from college and follows the ups and downs of their lives, as they discover what they really want to do, and as they discover what they mean to each other. Not great, but some good observations on youth, searching for one's place in the world, the power of friendship, not giving up on each other, etc. At times I wanted the book to speed up, but in the end I was quite enamored of both characters.
