Green Mars (Mars Trilogy, #2)

The sequel to Red Mars, quite nice. Not as good as Red Mars, I think, a bit more into itself. The biggest problem is that Robinson made a lot of great characters in Red Mars and won't give them up: through the miracle of immortality, they're permanent. Still, he does let some of the characters develop, and the plot is unfolding nicely. I can't wait until Blue Mars comes out so I can finish it up.
