Magical fiction

Magick fiction; novels, comics and other works of fiction which help the reader learn about magick. Different things are going to be good for different people, but this is a general guide. Some of the creations listed here come from people who believe in magick. Others from unbelievers.

By fiction we mean TV, books, comics etc.

(will flesh out later, I'm just brainstorming for now.)

Magick-Related

Snowcrash by Neal Stephenson has some interesting aspects regarding Namshubs and Sumerian mythology.
(Out recently!) Quicksilver (also by Neal Stephenson) appears to be about alchemy (among other things). I've not read it yet, so I'll update this when I have!)
Neverwhere, American Gods, series by Neil Gaiman
The Mists of Avalon by Marion Zimmer Bradley. A book about King Arthur. In the acknowledgments, Bradley admits that she has selected the theories "that best fit the needs of fiction", for information on pre-Christian religion "has been made conjectural by the determined efforts of their successors to extinguish all such traces".

More subtle representation of ideas

Jorge Louis Borges: Noted Argentine writer, poet, and philosopher. His works are often described as "Magical Realism" and deal with such subjects as space, time, perception, infinity, the nothingness of personality, heretical religious sects, Kabala, and other such esoteric subjects.

Dune Series - Frank Herbert: The worm juice (water of life) allows people to access the memories of all their ancestors. akashic records anybody?

The "Amber" books by Roger Zelazny: In which the main characters move between worlds by changing them very slowly, and reality is defined by the "primal pattern" and all worlds are just a reflection of it (a little like the worlds of the Tree of Life)

The "Discworld" series by Terry Pratchett: A series of excellent satirical works. The ideas and themes of the books (especially the 'witch-type' books) follow the basic ideas of witchcraft.
