Judging from your comment, you may find it intriguing to take a peek at the authors and books listed in Appendix N (Inspirational and Educational Reading[0]) from the Advanced Dungeons & Dragons Dungeon Master's Guide (1979). If you have any interest in the fantasy roleplaying sphere, this list should be all the more interesting.

On your latter question, I don't see much discussion surrounding The Magus by John Fowles (1965), which is one of my favorite fiction novels of all time.
