Full of novel ideas. The book is slightly overlong - the last section being a bit tedious, and some of the relationships between characters made it seem like a hi-tech soap opera at times. Apart from those very slight blemishes, it's definitely a Must Read for science fiction fans.

Overall, I'd give it 4.75 out of 5.
