I didn't care for this book. I made it to the end, but only because it won a Hugo Award. I kept waiting for it to get better, but it never did. If it wasn't for the Hugo, I would've quit after the first 100 pages or so.
Reading this book felt like reading a sequel. It's like there should've been a book before this one that set up the world more completely.
I didn't like any of the characters. It was interesting to see the story from different points of view, but it would've worked better if I had actually cared about any of them.
