'RICH, AUTHORITATIVE, AND HIGHLY READABLE ... [A] _TOUR DE FORCE_' DAVID KYNASTON Chairman Mao was a librarian. Stalin was a published poet. Evelyn Waugh served as a commando - before leaving to write Brideshead Revisited. Since the advent of modern warfare, books have all too often found themselves on the frontline. In The Book at War, acclaimed historian Andrew Pettegree traces the surprising ways in which written culture - from travel guides and scientific papers to Biggles and Anne Frank - has shaped, and been shaped, by the vast conflicts of the modern age. From the American Civil War to the invasion of Ukraine, books, authors and readers have gone to war - and in the process become both deadly weapons and our most persuasive arguments for peace.
