As a general rule, Heinlein novels are either really controversial (The Moon is a Harsh Mistress), really meta (The Number of the Beast), really fun (Citizen of the Galaxy), or some combination of all three (Starship Troopers). Farmer in the Sky is one of the really fun ones.
This novel was written before the Apollo 11 moon landing, but it read like something from an alternate reality long after that pioneering era, where the space program never slowed down. For that reason alone, it was a fascinating book. You can really see how it inspired people back in the 50s and 60s to reach for the stars.
More than that, it was really fascinating to get into the knitty gritty of colonizing a world like Ganymede. This is one of Heinlein’s juveniles, so he doesn’t get too technical, but you can definitely tell that he did the research and built a plausible near future world. More than that, it’s the kind of world I’d actually love to live in. Ganymede is the new frontier, and the colonists who settle it are pioneers in every sense of the word. Not everyone makes it, of course, but those who do are rugged, resourceful, and remarkable.
This was a really quick read. There was a lot of little stuff that dates it to the 50s, like gender relations and the prevalence of the Boy Scouts, who are sadly no longer a cultural force in today’s society. None of it bothered me or threw me out of the story. If anything, it added to the novel’s charm.
Heinlein knows his stuff. This was a really fun book. If you’ve never read any Heinlein, Farmer in the Sky is a good place to start.
