This book was one I had mixed feelings on. My dad handed this to me and told me it was one of his favorite books from his youth, that it was the book that opened his eyes to the thoughts of exploring the world outside earth. It was fairly well written, although due to it's novella status left a LOT to the imagination, and left a lot of plot pieces wide open to interpretation. That said, it was written in 1948, long before traditional sci-fi and long before ACTUAL space exploration. The kind of predictions, the kind of speculation, the kind of social commentary is absolutely outstanding for the time period. This book seems bland now, but at the time must have been mindblowing. I appreciate what this book is all about and love it for it's ingenuity.
