The book has been translated into many languages from the original French version. It was also made into a play and a movie, and the children's cable channel Nickelodeon in America ran a cartoon series in the mid-80s based upon the prince, his rose, and his adventures.

Its one of my favourite books of all time, and as much as it may appear to be a children's book, the dedication very correctly asks you that it be read by adults too. Among the many quotable quotes it has, it asks of us not only to reclaim the innocence of our youth but also exposes to us some of the things which are truly important in our lives. But really, I can't say enough about it here, you will understand all by reading it. Also, I suggest finding a paper copy, as blaaf's posting of the entire text cannot offer you the author's own illustrations, which greatly enhance this beautiful story.

The book is also an inspiration for Depeche Mode's Violator album.
