The Illuminatus! Trilogy
Robert Shea and Robert Anton Wilson. DTP. .
(Originally in three volumes: The Eye in the Pyramid, The Golden Apple, and Leviathan).
This work of alleged fiction is an incredible berserko-surrealist rollercoaster of world-girdling conspiracies, intelligent dolphins, the fall of Atlantis, who really killed JFK, sex, drugs, rock'n'roll, and the Cosmic Giggle Factor. First published in three volumes, but there is now a one-volume trade paperback, carried by most chain bookstores under SF. The perfect right-brain companion to Hofstadter's Gödel Escher Bach.
