Beyond This Horizon is a weird, short novella, with some of Heinlein’s earliest ideas presented on libertarian ideals. I find that I have little opinion on it after finishing it because the story was not very memorable. At first, I loved how it started. Much relief after giving up on Number of the Beast. It felt like real Heinlein, from the early days.
The plot revolves around a 22nd century future where people are armed and offenses must be forgiven to avoid a duel. And there is almost NO crime. Imagine that. Toward the middle, I wasn’t sure where the story was going. It moved into genetic engineering and seemed to lose its plot after a short gun battle between the protags and a group of anti-establishment renegades who the protags should have sided with, given the first half of the novel.
In the end, not a favorite, but pretty solid Heinlein early story that I wouldn’t need to read again.
