I've switched from reading the novels in my own language (German) to reading them in English.
I particularly like the tiny bits of German-sounding words or even German words in the novels, for example in The Amazing Maurice ...
Now, last week a friend of mine showed me a calendar with pictures of the Hogfather TV series ... up to then I didn't even know about it. Seems that PTerry himself is in there ! (Wikipedia has a small page about it).
Last novel In read was Thud! I honestly dislike the horrible american & German cover, but the original English one is superb. I'd like to have it as a wallpaper.
What few people know is that Rhianna, his daughter (don't know how many children he has), is an editor of a gaming mag, as far as I know, and that she wrote a novella for Beyond Divinity. It shipped with the British versions of the game, I think. Currently unavailable otherwise. She has a nice humour in it, too.
I've got a signed book - from the only time he was in Cologne. He even was in my home town, Leverkusen, near Cologne, when a novel of him was played on stage. Sadly I got this info only few days after the event.
I'd still like ti kick myself for that (to me it's like hgetting to know that Jeff Smith, author of Bone, was actually here in Bonn, south of Cologne, on his signing tour, and I got to know it only a week later ! I was almost banging my head on the next wall for that.)
In short : I love his books, and the older he gets, the more he writes, the better his books become.
