Well, I don't know what I was thinking, but I finished it.
Overall, I'm not too sorry. It was a bit of a slog there, but I don't think it was a real misdirection of the author's intention. In fact, I think that 100 pages shorter, the book would have been very good. I could have used a lot less of Nan's point of view--it was the weakest-written portion of the book (everything she thinks is spelled out and repeated and simplified), and adds the least to the story. Sara's viewpoint doesn't add very much, either, but she gives a dash of perspective on the family, since she's the most unlike the Setons. There's only a dash of Sara--there's WAY too much Nan.
Anyway, I did it. And then today we went to the Middletown library used book store. I got Inventing the Abbots, short stories by Sue Miller (I've never seen the movie), The Rapture of Canaan, which was the first Oprah book I ever read, and pretty good, and another Kazuo Ishiguro book (though I don't have The Remains of the Day yet).
But before I start those, I'm going to reread Never Let Me Go for book club. Next goal--go!
