This was a lot better than I expected it to be. Low expectations: It seems have to been one of Norton's last solo works, it's definitely more mystical/naturalistic than I prefer, and the protagonist is female. (That last is a purely involuntary, illogical reaction that I'm not sure how to explain but yet affects my enjoyment of any book.)
It was still dissatisfying in some ways. I don't sympathize at all with the Industry Is Evil, Human Culture Is Evil, and Women Are Awesome And Men Are Inferior/Bad/Stupid/Pigs tropes that Norton leans toward in a lot of her books. And since this one was a later book, I'm less tolerant of those old-hat ideas in this book than in her earlier work.
Also, this seemed to be more of an adult-audience book than the vast majority of what Norton wrote. So when it set up some harsh circumstances - a "bride lottery" in which women were conscripted and men had no choice of bride - somehow I expected different handling. For example, she drew a comparison to a slave auction. It was superficially similar, but she wholly overlooked some fundamental differences. That kept it from ringing true - not the situation, not the emotions, but the writing.
On the plus side, though, there's a lot. It was longer than most of Norton's books, over 300 pages. The conflict was more complex than her typical plots, and there was more sustained action than usual, particularly in her more "dreamy/mystical" stories. The pacing really felt different, and it kept me engaged.
The protagonist did not irritate me once. Not once! This is notable, since as aforementioned I prefer males, and I tend to be critical and dislike stereotypical action. Now, I didn't really *like* her much either; but she was admirable and really, more adult. The male protagonist - whose part in the plot was admittedly a major reason I got this book - was quite interesting as well. Seeing him through her eyes was really well done. And somehow Norton even subverted the Men Are Whatever trope when handling him! A memorable character.
In addition to all this, there was still Norton's trademark inventiveness of peoples and worlds. There was much to discover about the world in the book, and it was all interesting. A weakness of the plot might be that it was a bit diffuse, but that allowed for journey, coming-of-age, spiritual awakening (so to speak), and even battle elements to all be present.
I've really gone on too long. Boiled down, this is a good book because it kept me interested and when I put it down, I was satisfied.
