I like this book. A very short story, well illustrated and full of action that can get young readers introduce and to like science-fiction, which is not the most frequent genre in children literature. The plot is simple enough, but still alright and there is just not any time off, so even if some kids are not very attract by reading, this action pack book can allow them to see a different style of books, that might catch their attention. Different, original and well done!
