The Electric Kool-Aid Acid Test
by Tom Wolfe
Finally finished the bastard---it was a real slog. I'm sure the writing is some people's cup of tea, but not mine.
The most interesting part of it, and the only part that has stayed with me strongly, was the description of how it all went sour---the point where the civil rights movement stopped being cool and was dropped in favor of drugs. Definitely a warning.
