Slaughterhouse 5 by Kurt Vonnegut[1969]
We said: Named after a real-life slaughterhouse where Vonnegut was held captive as a prisoner-of-war, Slaughterhouse 5 is an intimate, anti-war masterpiece. Only Vonnegut could channel horrific experiences endured into a fictional novel: 'How nice -- to feel nothing, and still get full credit for being alive', he writes.
They said: In my opinion it contains many key elements of a classic dystopian: world war, an unreliable narrator, intersection with sci-fi, questions of free will, and the perception of unimportant human life.
