All Quiet on the Western Front.
I had read it as a boy, and I had forgotten how good it is.
A book that I thought was interesting out of the many anti-war books written after WW1 was by Robert Graves, it was called, Good-bye to All That, it was an autobiography focusing on his WWI experiences. It is interesting for it is a critique of British society at the time and since Robert Graves was so much of an influence on the pagan movement with his book, The White Goddess. His accounts of the flesh eating rats in the trenches during WW1 has stayed with me. Another good anti-war book from WW1 was, Johnny Got His Gun, by the American writer Dalton Trumbo. It involves the story of a totally disabled young man unable to communicate after getting caught in an artillery shell blast. I always have liked, Cats Cradle, by Kurt Vonnegut, it is about the allied bombing of Dresden in WW11.
