I found the author made some good points but was totally wrong on some others. I thought his view on charity (in the chapter on Social Morality) was excellent.
The Great Divorce
This book was a fantasy about the difference between heaven and hell and our choice in the matter. It was short but interesting.
This one was tough going for me. The author used many logical arguments that I found difficult to follow. I made a note that I had enjoyed Appendix B, but I don't remember what it was about.
