The Sense of an Ending by Julian Barnes

This book starts as a brief bildungsroman, but it develops into an intriguing story about regret and whether you can go back to reevaluate the past. Anthony Webster is a young man whose girlfriend dumps him for one of his best friends. When that friend later commits suicide, Anthony puts the whole episode out of his mind. But forty years later, he receives a strange bequest that prompts him to reexamine his past. While the book comes together in a thought-provoking way and was generally enjoyable, there's something a bit pat about the whole thing.
