marquis de sade? Read some of his works in a humanities course back in university...um....interesting reads to be sure.

Lord of the Rings definately!

Um, I would suggest the Avalon series by Marrion Zimmer Bradley for something different (fiction -- historical / fantasy). In order:
- The Fall of Atlantis
- The Forest House
- Lady of Avalon
- Priestess of Avalon (touches on some characters in Lady of Avalon)
- Mists of Avalon
