This may sound odd, but the book M*A*S*H* was a huge part of my high school years. I read it after the film came out and before the TV series.   While the book was not as strongly anti-establishment as the film, it still opened up a world of rebellion in my eyes.

There was another book that I remember from high school - Pissing in the Snow. Aside from the great title, it was a book of folklore that opened my eyes to American cultures beyond my world in NJ.
