The Illuminatus! Trilogy, by Robert Shea and Robert Anton Wilson
I think my wife hit it. It's interesting to a teenager, but not so much to me. I read the first 'book' of the three. I liked the secret submarine with stealth technology (that didn't work) tracking the crab excavator robots looking for treasure in Atlantis, and f**king an apple statue with a woman inside as an initiation rite, but all the non-linear hallucinations got tiring. I appreciated the self-mockery of the short section that quotes a reviewer panning the book for not doing non-linear style as well as a more famous author. Another swap from paperbackswap, and it's destined to return, hopefully sent to a teenager.
