It is a children's story and its pages are adorned with Antoine de Saint-Exupéry's famous illustrations, but closer reading as an adult reveals major themes and its allegorical nature. The story is thought to be partly autobiographical, and the Prince acts as a means to critique society and demonstrate the strangeness of the adult world.
The book I purchased also included Letter to a Hostage, an open letter for Saint-Exupéry's Jewish friend Léon Werth, who was trapped in Europe and awaiting passage to the United States. The Letter was published in 1943, just two months before The Little Prince and is a similar critique of society, though less fantastical.
Some striking passages:
"All grown-ups started off as children (though few of them remember)." p.3
"This asteroid has only once been seen through the telescope: by a Turkish astronomer, in 1909. At the time, this astronomer made a grand presentation of his discovery before an International Congress of Astronomy. But since he was wearing Turkish national costume nobody would believe him... In 1920 our astronomer repeated his demonstration, wearing elegant evening dress. This time everyone accepted his proofs." p.14, 16
"To forget a friend is sad. Not everyone has had a friend." p.17
