In addition to the ones already mentioned, here are a few I have read:
Elie Wiesel, Night, Dawn, and Day (trilogy of Wiesel's experiences of the Holocaust. Night is quite a classic Holocaust memoir)
Evelyn Waugh, Sword of Honour trilogy (set in the Mediterranean and originally published in separate volumes as Officers and Gentlemen, Men at Arms, and Unconditional Surrender, but intended by Waugh to be read in a single volume)
Paul Watkins, The Forger (about an American art student in Paris pressed into service for the French resistance to forge artworks)
These are more thriller-type books than classic literature:
Alistair MacLean, The Guns of Navarone and its sequel, Force Ten from Navarone (there is a movie too)
Jack Higgins, The Eagle Has Landed and Sheba
Hope these are helpful :001_smile:
