Wow!!! What a great book about the frailty of man. Uncle Screwtape (a demon) writes a series of letters to his nephew (a lesser demon) about how to win the soul of a human being. I was listening to this while working on the treadmill. I initially turned it off as the material seemed evil and disturbing at first. However, the more I listened to it, the more intrigued I became. C.S. Lewis is a religious writer but do not let that keep you from reading this book. This is more about public policy and social values. It applies today just as well as it did in the 1940's.
