Pebble in the Sky

Well it's written by Asimov, so of course it's good.  I cringed a bit when Schwartz got telepathic powers -- surely Asimov could have invented something else to achieve the same result -- but it was overall a good book.  It did not so much keep me excited for the next page as the next paragraph.  The story was full of wonderful little details, like how people in the distant future have a different skull structure, fewer teeth, and a smaller appendix.
