I read this as a kid, and it was a long time fave from a distance. Coming back to it as an adult, it is...way, way problematic. As others have noted, the female characters are less "characters" and more "wish fulfillment." They don't behave, at any point, realistically. They are objectified throughout, and I do mean almost every female character gets a lens of objectification thrown on them, either for the positive or the negative.
I wasn't really willing to let that go, per se, but there are aspects of the book I was specifically looking for, and so I kept reading to find them. And it just...kept getting worse. I'd noted repeatedly that where I'd expect, say, Clarke or even Heinlein to toss some gay shit in there, Anthony was avoiding it. At one point, there's a mention that a major point of space travel is husbands fucking other women while their wives watch secretly...and absolutely no mention of the reverse, of women together, of men together. The explicit tone is that the women are the source of entertainment, save the cuckolded wives, who are titillated by their husband's prowess.
And then, at one point, Anthony explicitly says that a character must be male, for no woman would conceive of marrying a woman, and I rocked back a little. I can hold to a convention of a biased narrator, even a third person biased narrator since the novel only shows the protagonists perspective ever, but the author being that explicit in an aside indicates that the views I'm reading are the word of god, not the word of a flawed character.
So, essentially, it is an incredibly sexist power fantasy couched in SF terms. All the moralizing always comes down to situational ethics, and amounts to precisely nothing. No lesson is gained, no progress is made, the story itself goes nowhere, and the vast majority of the going nowhere is done in the most sexist, bigoted way possible, even as the author attempts to look like he's discussing bigotry.
If you want any reason to read it, Hermine and Mit are it. But beyond that...not really worth your time.
