What's up? I got my copy of the book (hardcover) and the first thing I noticed was the last message written in High Speech.

I DON'T want to know what it says, but HOW I'm supposed to get it. So far I'm reading Wolves Of The Calla, so I wouldn't know if there are some more letters used and explained in the other two books (the sixth and seventh) but I doubt it. So... ideas?
