The Great Divorce by C. S. Lewis (2001, Paperback)

In The Great Divorce C.S. Lewis again employs his formidable talent for fable and allegory. The writer, in a dream, boards a bus on a drizzly afternoon and embarks on an incredible voyage through Heaven and Hell. He meets a host of supernatural beings far removed from his expectations and comes to significant realizations about the ultimate consequences of everyday behavior. This is the starting point for a profound meditation upon good and evil. "If we insist on keeping Hell (or even earth) we shall not see Heaven: if we accept Heaven we shall not be able to retain even the smallest and most intimate souvenirs of Hell."
