I just finished reading Robert Heinlein’s Space Cadet. I enjoyed reading it, but it was more entertainment than anything else. It definitely did not bring up the concepts that Stranger in a Strange Land did. The book follows Matt, a cadet in the Patrol. The Patrol is a military-like organization above the military in charge of keeping the peace. It is entrusted with the most powerful weapons in order to keep them from being used, because weapons of this strength cannot be trusted to the military. Heinlein’s portrayal of the future is fascinating. While there are some errors, he accurately describes many things and writes very little that is wrong.
