I didn't really like it that much. I'd give it a 3 if 10 was the highest number and 1 was the lowest. There wasn't a lot of continuity with character so it was hard for me to get into it. But a friend loaned it to me so I felt obligated to read it. It has a really good premise and it created some cool thoughts about civilization and stuff but it really wasn't one of the better books that I've read even though it's supposed to be one of the great sci-fi books. Kit.
