For the novitiate science fiction reader, a harmless phantasy about young Eddie Blow and the occupant of an Astral Rocket Disk which lands on his grandmother's farm in upstate New York. As a Junior Scientist Explorer from the planet Martinea, ""Marty"" brings a working knowledge of Earth's ways, learned through special equipment. Quests for more information lead Marty through such amazements as a Boy Scout Jamboree, fishing trips, the difficulty of being explained to the neighbors- while Eddie finds out about secret power Z. which runs the space ship and just about everythings else on Martinea, gravity boots, a dictionary box etc. Fluffy but funny.
