The Little Prince is a novel by French aristocrat, writer, and military aviator Antoine de Saint-Exupéry. It was first published in English and French in the United States by Reynal & Hitchcock in April 1943 and was published posthumously in France following liberation; Saint-Exupéry's works had been banned 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 book, The Little Prince makes observations about life, adults and human nature.
