A gripping narrative of friendship and exploration, and an homage to Antoine de Saint-Exupéry, an unforgettable writer who touched the lives of millions of readers, and who was able to see the world through the eyes of a child.

In the 1920s, long before he wrote The Little Prince, Antoine de Saint-Exupéry was an accomplished pilot. Along with Jean Mermoz and Henri Guillaumet, he was chosen to pioneer new mail routes across the globe. No distance was too far and no mountain too high—each letter had to reach its destination. The three friends soared through the air, while back on solid ground, they dealt with a world torn apart by wars and political factions.
