Science fiction review: Kim Stanley Robinson’s 2312. - Slate Magazine
Go to the link for a gushing review of a new book by a pretty well known science fiction writer. Personally, I didn't find the first novel in his Mars trilogy to be all that great, although there are parts of it which have stuck in my memory. I didn't go on to try the next two books.
The review gives enough plot details to make me think the new book suffers at least one of the problems I had with the Mars novel - he seems wildly optimist about the speed of technological change in a way that just feels rather improbable. It always seems safer to me for science fiction writers to not be so specific about their future chronology, and leave the reader guessing a bit as to how far in the future we are talking.
