U Principellu, in Corsican language.

If you read the story of the author, you would have wondered if the Corsican edition has ever been published. Saint-Exupéry’s last flying was to collect intelligence on German troop movements in and around the Rhone Valley preceding the Allied invasion of southern France. He took off in an unarmed P-38 on his ninth reconnaissance mission from an airbase on Corsica. He did not return, dramatically vanishing without a trace. Just like the Little Prince.
