Emmanuel Guibert already made a lot of different books. Not long ago I read Alan's War. A book about American G.I. Alan Cope's memories of the Second Worldwar, written and drawn by Guibert. A very moving story of a soldier who was transported to France to fight against the enemy. The images are done in subtle grey-tones which give the story even more dimensions.
I really recommend this book. Language can not be the problem, Alan's War is available in French, English and Dutch.
