I came across this book a couple months ago. I just read it a couple weeks ago and found it to be quite enjoyable. The summary from the book's jacket is below. The author is Mitch Albom. I found it to be a really sweet book that shows us that seemingly insignificant lives actually do have meaning.
Eddie is a wounded war veteran, an old man who has lived, in his mind, an uninspired life. His job is fixing rides at a seaside amusement park. On his 83rd birthday, a tragic accident kills him as he tries to save a little girl from a falling cart. He awakes in the afterlife, where he learns that heaven is not a destination. It's a place where your life is explained to you by five people, some of whom you knew, others who may have been strangers. One by one, from childhood to soldier to old age, Eddie's five people revisit their connections to him on earth, illuminating the mysteries of his "meaningless" life, and revealing the haunting secret behind the eternal question: "Why was I here?"
