Finally reading this! I’ve owned it for ages.
Wow, what a neat book! I can really see why people were so affected by this. It’s a little dated in spots (it doesn’t deal with homosexuality much at all, really) but I enjoyed it. Bits of it are kind of cheesy but I loved the way Heinlein created such a radically different culture for the martians and looked at how it might interact with the culture of humans. Wonderful!
