My favourite book of all time is "All quiet on the western front" by Erich Marie Remarque. It's an anti-war-book about WW1 that's just gripping from start to finish.Thanks, i am also read this booksI also really like George Orwell's "Homage to Catalonia" which is about Orwell's time fighting facists in the Spanish Civil War.
Stephen King's "The Stand" is also a book I'd recommend reading on long summer weekends.
