I read The Little Prince in French along with an English translation. It took me quite a bit longer than it should have. My French is rusty from disuse. It's been a decade since I went to Paris for a study abroad program. I'm ashamed to say I found even this small, simple book a challenge to read. But I'm glad I read it. 
 Le Petit Prince is the story of a man who is stranded for several days in a desert with a boy who claims to have come from a tiny asteroid. The boy -- the little prince -- describes his journeys and the people (mostly asinine adults) he's met along the way. This sounds simplistic, but every part of the boy's story is designed to reveal some facet of the author's experiences or human nature in general.
