This is a collection of four juvenile science fiction stories written by what I can only describe as the Grand Master of the genre. They captured me as a child and a quick recent visit as an adult has not changed my opinion. When Mr. Heinlein finally did start writing adult stories, (Stranger in a Strange Land, To Sail Beyond the Sunset, Puppet Masters, Time Enough for Love, and many more, he was still the Grand Master. If you get this far and want to have an opinion any of his other works please PM me and I will try to help. He is becoming increasingly dificult to find since he passed away and I am not certain his widow (Virginia) is still alive. He had no children and his papers are housed at UC Santa Cruz in California. We will probably not see any more new publication.
