Moral allegory and spiritual autobiography, The Little Prince is the most translated book in the French language. Technically, this book is suitable for any age, children and adults, but I doubt that most would completely understand it for children. It is said that this book should be read 3 times in one's life: as a child, as a young adult and as an older adult because as we grow older our perspective changes, and thus we become able to appreciate things in different ways.
I'd say the group of teenagers of the club enjoyed this book a lot, especially because there are many themes in the book that are relative to love and friendship, and everyone but especially teenagers give purpose and meaning to theirs lives through the relationships that they form. Also, the students connect with the idea present in many parts of the book that adult people are preoccupied with things of little real value and we become less creative and imaginative, as we get older. For these reasons, I really recommend this book to anyone who wants to enjoy and think about what it is important.
