The Great Divorce by C. S. Lewis

The Great Divorce starts with a man who has been walking through a grey city in the evening for a long time.  It's implied at the time to be hours, but later in the book, it's hinted that he's been there for a lot longer, anywhere from a few days to millions of years.  It's a dismal place filled with abandoned factories and the like.  He gets bored quickly and sees a line leading to a bus stop.  It's a long line, but he goes to the end of it.  People start leaving the line in front of him.  One leaves because he keeps getting insulted and hit and can't bear it long enough to get to where the line is going.  A couple go because they have no need for the line because they have each other.

He gets on the bus and talks to a few people.  When he gets off, he emerges in a whole new world.  he bus has flown to a wonderful new place where everything is several times more real.  The world is also many magnitudes more real than himself and the other passengers, and because what is fake cannot really affect what is real, he cannot move the blades of grass nor pick a daisy.  It is as if everything is made of immutable diamond.  This is heaven, and the place before was hell.  As soon as you cast off the things that were holding you down, you become solid like the rest of the world.

This interpretation was extremely fun to read.  At every turn, there was something or somebody new and fun.  A couple of the people who rejected heaven I found I had an unsettling resemblance to.  I'd like to see some comments as to whether anybody else saw themselves in the laughable caricatures of sinners.  I know that he wasn't intending it as an actual depiction of heaven, but his heaven sound like a place I'd really, really like to be at.
