Well, although "Inherent Vice" is excellent, I'd hazard the claim that it's less true to, or memorable on, the counter-cultural 60s (and just after) than Maxine Kong Kingston's masterpful "Tripmaster Monkey," not to speak of such evocative non fiction as Wolf's "Electric Cool Aid Acid test" and Mailer's "Armies of the Night."
JAMES ELLROY - Blood's A Rover is a good fiction book during the counter-cultural sixties.

Originally published by Random House in 1969, Nog became a universally revered cult novel and a symbol of the countercultural movement.
Writing about Nog, Pynchon proclaimed: "Wow, this is some book, I mean, it's more than a beautiful and heavy trip, it's also very important in an evolutionary way, showing us directions we could be moving in - hopefully another sign that the Novel of Bull**** is dead and some kind of re-enlightenment is beginning to arrive, to take hold. Rudolph Wurlitzer is really, really good, and I hope he manages to come down again soon, long enough anyhow to guide us on another one like Nog." -Thomas Pynchon
