About the only other things I knew going in was that I had really liked Vinge's Cat book (not actually books about cats, books about a dude named Cat, sorry), that she had at one point been married to Vernor Vinge, and that I was pretty sure that years ago I had heard a rumor that her husband was a total POS.
...turns out that I was unable to find anyone saying anything bad about Mr. Vinge, but her current husband is Mr. Banned-From-Wiscon himself, so apparently I have been thinking poorly of Mr. Vinge for years for no reason. Sorry, sir! See, this is why this stuff needs to be out in the open, not whispers.
Anyway, as for the book itself: it's well-written, I didn't hate any of the characters, the world-building and plot mostly hang together (at least until the very end, anyway), the concepts are interesting, there is no compelling reason I shouldn't have liked it, and yet I never quite managed to get into it. It isn't even that it's not my thing, because it *should* be my thing, ( and yet )
Anyway, short version: You could probably do a Snow Queen retelling that used the story in a way that worked for me (I should really get my hands on The Raven and the Reindeer) but this was not it; and I would totally read an entire novel about Ngenet and Jerusha (as long as Jerusha got to finally show a tiny bit of minimal competence which she never actually did in the book - a plot line about how she is unfairly treated as incompetent because she's a woman doesn't work if she never actually is competent); and I should have listened to my instincts and run when the summary on the back ended with "...the one man fated to love them both."
...interestingly I also read Makt Myrkranna today (having never read Dracula all the way through) which is also about a pretty, innocent young man who gets lured into the clutches of an ancient powerful beautiful cold devouring woman and her consort, and how his true love traveled across a continent to rescue him and save the world, but somehow I don't have any of the aforementioned complaints about it. A++ worldbuilding, dude does not let heterosexuality make his choices for him, lady makes reasonable choices based on the knowledge she has at the time and caring about him as a human being she is fond of who is in trouble.
I also read Pale Guardian, but I think that's actually the first Ashers book in which nobody ever has to rescue James, so it doesn't quite fit the set.
(I have been sick lying on the couch all day, which is why all the reading suddenly. Also I still have four more library books and two fmk waiting lalala.)
