Another imaginative science fiction story by Robert Heinlein treats its world of the future in delightfully human terms. A senior in a New York high school some centuries hence, Rod Walker has taken an advanced course in survival training (an integral part of emigration to other planetary systems that is becoming necessary) and is about to face his solo survivor's test. His sister Helen, a captain in the Amazons, gives him odd but sound advice that seems to corroborate all Rod's instructor, the seemingly hard hearted "Deacon", has always maintained, and so off Rod goes, lightly clothed and gunless, to his new planet. It turns out to be an earthy place and the terrain Rod finds himself in is strangely like Africa. He runs into other students and when there's a hitch in their return and they must stay, the boys and girls band together to form a town and to make a new spot of civilization. There is a real social saga; Rod is elected the second mayor, there are marriages and families and the whole smacks of a decently, dangerously worked out phase of American pioneering. When Rod must return to Earth, as an adolescent still, he is told by the Deacon that he can and must endure this too. Realistic, thought provoking, humorous.
