The Great Divorce is one of the simpler of Lewis' collection. Well read and easy to listen to. There are some brilliant concepts of heaven and hell. The abolition of man is quite a work but has dated a bit and is Lewis at his most academic. Overall well worth a listen
CS Lewis' works are such classics in the Christian world of the 20th century. People who used to be skeptical of Christians using fantasy were won over by Lewis. Now buckle your seat belt and get ready to be won over (if you dare) to Lewis's view on hell. The Great Divorce is fiction (even says so at the end--oops, spoiler alert!) and therefore Lewis feels free to conjecture what the afterlife might be like. You'll be introduced to his musings over ghosts, purgatory, and the size and significance of hell (or lack of real significance). Are you baffled by Rob Bell's "Love Wins"? Lewis's book is in some ways a precursor to that.
The other book in the series, The Abolition of Man, is forgettable. Reading this one made me feel like I was walking into the middle of someone else's conversation on a topic that I had no reference point to understand what was going on. Perhaps meaningful to boarding school students and faculty in 1940's England, this is one we could leave off the shelf.
Yes I love C.S. Lewis
I picked the wrong book - it was difficult to follow ... was expecting something else
