Auzou Papi and Lucien's funny war book t1

1940. Papi is a former poilu, still very angry at the Germans. For him, nothing beats a good trench! His grandson, Lucien, tries to explain to him that this new conflict has nothing to do with the Great War. One day, Papi hears General de Gaulle's appeal on the radio. Up like a cuckoo, he decides to join the Resistance in London. With courage and a good dose of recklessness, Lucien and his grandfather set off on an incredible road-trip through France, on a path strewn with pitfalls.
