I have a copy of John Cleese reading it on CD. He does one heck of a job. I play it on a regular basis - every time there is some nugget of truth God brings to mind for me to apply.
It’s very condensed.
I would like a set of the trilogy that starts with “Out of the Silent Planet” for starters. Haven’t read that for a long time. I do have Screwtape on the shelf right behind me.
