Brave new World is a great book. I thought of another: “The Long Walk”, by Slavomir Rawicz. It’s the story of a Polish army officer who was captured and sent to a work camp in Siberia. He, along with a group of other prisoners, escaped and walked (!) to India.
It’s allegedly autobiographical, though there are some records that suggest it can’t have been entirely true. Either way, i can’t recommend it enough. Incidentally my grandfather was a Pole and was also captured and sent to Siberia, and – like the author – eventally moved to Nottingham after the war.
