This is one of those books I think I would have loved 25 years ago. As it is, I liked it, and I wasn't bored by it, but not quite enough to go for the GoodReads interpretation of four stars, or "really liked it". And perhaps I was a tiny bit disappointed, after having heard so much praise for it for a long time.
Still. Not a bad story, and I'm glad I read it. I just wish I'd had the opportunity to do so back when I was really into all this wonderful early space exploration sort of science fiction.
