The only reason this didn't end up with 4 stars is that it was too short, leaving some narrative feeling cramped while other background work felt unfinished. It was still in good shape, but it ended up lacking polish.

This is what people should mean when they say “Lovecraftian Horror'. It's not about being part of the mythos, it's about feeling afraid of the unknown and unexplained in a universe that doesn't care.

A definite improvement over the previous book. Better pacing, better storytelling, better writing. Somewhere near the end, it actually made me interesting in the overarching story again, which I wasn't really expecting.

tl;dr: Heinlein wrote a great book about a powerful alien coming to Earth and learning about humanity as an outsider, but unfortunately he only had one hand on the typewriter while he wrote it.
