I would recommend, “The Five People You Meet in Heaven” by Mitch Albom.
I really enjoyed this book; it might sound depressing as it begins with the death of a character who ends up in heaven and he meets five people who were very instrumental in his life. It is a reflective book and thought provoking and not in the least bit depressing. It is only a relatively short read for those that don’t want to read thousands of pages.
