Homage to Catalonia, George Orwells memoir about the Spanish civil war. I never read memoirs or autobiographies, but I am very glad I have read this one. It gives a good insight into various aspects of the civil war, as well as Orwells personal views (and his sigarette addiction). On top of that, it is at times hilarious. And it is almost unbelievable how many things happened in just 6 months.

Highly recommend it if you're into history or politics or love Orwells other works.
