The Little Prince, by Antoine de Saint-Exupery

A novella by French aristocrat, writer, and aviator Antoine de Saint-Exupery. 

It was first published in English and French in the US in April 1943. It was banned in France by the Vichy Regime.  

The story follows a young prince who visits various planets in space, including Earth, and addresses themes of loneliness, friendship, love, and loss. Despite its style as a children's illustration book, The Little Prince makes observations about life and human nature very much suitable for grown-ups.

The Little Prince became Saint-Exupéry's most successful work, selling an estimated 140 million copies worldwide, which makes it one of the best-selling and most translated books ever published. It has been translated into 301 languages and dialects. 

The Little Prince has been adapted to numerous art forms and media, including audio recordings, radio plays, live stage, film, television, ballet, opera, and a candle.
