Story was mainly about a young boy who lives in a small planet that had travelled to different planets and different kinds of people/creatures. He's a very curious child that never lets his questions left unanswered. His encounters make us realize different things, like what we should and should not give importance to, and what things matter, and so on.
It was a very popular book, and I don't wonder about that because it was indeed fascinating. I like how it was narrated . . . it was unique. It may seem to be a simple children's book but the messages in its story make's one have some reflections. Overall I consider it really wonderful!
