Space Cadet

This is one of Heinlein's Juveniles. It's strong evidence in support of the saying "The golden age of science fiction is 12." The science is authentic (except for Venus being hospitable for human habitation and having its own intelligent native species), the characters are simplistic, the story is a little sappy. (Sappy is a word that probably was in the popular vernacular when Space Cadet was written in 1948). It's good old fashioned science fiction. I thoroughly enjoyed it.
