Illuminatus! trilogy

This is a kill or cure for paranoiacs, with an embarrassment of riches of conspiracies - complete with detailed evidence which is easily referenced. The mout outrageous and silly conspiracies are true (the Principia Discordia quotes are real), and some of the more believeable stuff is false. Wilson and Shea call it "guerilla ontology". Some people may find the viewpoint character changing so often to be distracting, but I enjoyed it as part of the trip. Its very seventies hippy culture, and very funny and perceptive. Its mind-blowing to realize it was written before Watergate and the Nixon insanities were publically known.
