At least two people in my life have started reading and chosen not to finish this book, which won the Nebula award for Best Novel this year (I'm curious about its non-appearance on the Hugo finalist list for Best Novel, and I suppose we'll need to wait for the data to come out to see why.)
That contrast fascinates me, though, because it's rare to see such diametrically opposed views of a book; on the one hand, "Best Novel" and on the other hand mulitple DNFs from people who ordinarily have pretty good taste.
