The last version of this über-useful thread seems to have gone the way of the dinosaurs, so here's a new one. Just finished Babel-17 by Samuel Delany, which I thought I'd read in the misty depths of time but apparently not as none of it was familiar. It was a very interesting read and challenging in places, not hard to see why it won the Nebula and not the Hugo. Now beginning Snow Crash by Neal Stephenson. I like it so far, though it does have a little "look-how-cool-an-author-I-am" element at times.
