ive been reading a lot lately and have been meaning to put together a little list of books that really should be read together:
homage to catilona/1984 - george orwell. written roughly about the same time. orwell's hatred of communism comes from his experiences with the anarchists during the spanish civil war.
black boy/native son - richard wright. if i remember correctly native son was written directly after wright finished black boy.
gravity's rainbow - thomas pinchon/the kindly ones - jonathan littel. insanely long, graphic, complicated books about nazis/WWII. not for the faint of heart or those not wanting to marry a book for several months.
those are the ones i can think of right now. look for more.
