Night Watch by Terry Pratchett

I just finished reading Night Watch - I've been on a bit of a Pratchett spree, I finished Guards, Guards a couple of days ago.

This is a book I wish president Bush would read. In fact he should read it twice, paying close attention to the bits about what good people do and don't do, about how there are certain rules you can't break and what they do to society when you do break them. And then he should get into a time machine and go back several years and do everything over again the right way. No torture, no stripping people of their rights, no might makes right, no being a tyrant.
