On "Night Watch" by Terry Pratchett ****

This book poses the question of what would happen if you were transported back in time so that your old self could teach your young self a few things about the world. Or at least, it starts off asking that question, and then it focuses more on space-time continuum and how to fix things in terms of the plot. But I like the question. And while I wasn't too keen on Pratchett's style early on, it grew on me, and then the plot kicked in, and about half way through he had me hooked. In the end, the book should leave readers with a lot of questions about fate, as time traveling books usually do, but Pratchett doesn't get into that too much--it seems more about government and politics than about questions of physics and metaphysics.
