The young backyard and cellar scientists are catered to in this one- the story of an American youth and a strangely human stranger, Clouar, from an intergalactic world who arrives in a flying saucer. The resultant occurrences from Clonar's language learning, his jumbled inner organs, the profitable interchange of customs (Clonar learns to dance), make for mildly interesting speculation. Then too, there is a pleasantly strong friendship between Ron, the American, and Clonar.
