Paperback. I think they're actually translating the books into German now, but I'm not going to read that. I prefer reading any book in its original language, as long as I understand that language. And I'm not very fond of German translations in general. Though I'll admit that the book translations are good enough, it's the tv dubbing that drives me up the walls. And I'll shut up now before I start ranting about that. Yup.
