Charles Stross' Accelerando is a terrific post-cyberpunk SF novel. Mainly telling the story about one family(If there's still that kind of social micro-structure) and how the technology (including alien life forms) reforms the entire solar system, Stross leads readers to the most fascinating and intricate future world.
I read the novel during the summer vacation and found it very profound. How deeply will the Internet change our world? Is there a limit of computer and A.I. development? Will the first encounter with alien intelligence (or other form of "incarnation"...whatever) ameliorate our civilization or the opposite? What is humanity if all of us can live forever?
A "must-read" in my list!
