I first read this in French for A level, forty years ago. I bought a copy in English, which has disappeared, and I rediscovered it in my local "tabac" about a year ago. It is a wonderful book, which every adult with average intelligence should read at least once in their lifetime.
The world from the perspective of the little prince is revealed in a way which is charming but not at all sentimental, and very thought-provoking if one allows oneself to be challenged.
I'm not saying any more than that - buy the book and discover it for yourself!
