and usually I don't make exceptions until a series is done (I get very weird about my bookshelf). But for some reason I did here. It is odd. I think it is because Roh gave me Nation in hardback last year, which in itself was ok because it wasn't a Discworld book, but that set a precedent for later Pratchett books as well.

I don't pretend to have a logical brain. Certainly not where books are concerned.
