I adore Sir Terry Pratchett's Discworld novels, and I've done something like 8-10 full readthrus. I'm currently near the end of one, in Unseen Academicals.
Usually when I read a Discworld, the first time is good, the second time is better, adn the third time it becomes very very dear to me.
I don't know if it was because as he got closer to the end, his last 2-3 novels he wasn't able to edit and refine as much, or if his style just evolved past the point where I love it quite as much, but while Making Money was great, Unseen Academicals is.....a little meh.
It may be the obsession with soccer, too. I dunno.
I dislike it less and less, and I actually appreciate a lot of it this go around, but it's still not a favorite. :(
And next up is Raising Steam and then on to Shepherd's Crown, which I know will make me cry again.
