The last (I think) in my reading of the Hugo Best Novel nominees. I had mixed feelings about this one. The main character (a teenage girl whose sight is restored by technological intervention) is well-drawn and pretty compelling. The awakening of the web (or whatever's going on here) is less convincing.
It's the first in a trilogy. I'm reserving judgment, but I don't think it rises to the level of Windup Girl or The City & The City.
