The Colour of Magic

I've just started this book. It's by Terry Pratchett, who I've heard wonderful things about. I really like his Discworld series, so I am trying to read it from the beginning, starting with this book. It's a tad hard to follow, and really not much like his more recent books (although his fondness for long, rambling footnotes makes an early appearence, to explain the geography of the Disc. It's on the back of four giant elephants, which in turn are marching across the back of a gaint turtle. It's really just that sort of book.) Still, it's rather clever, and Rincewind's in it, so I'm enjoying it so far. On that note, I can't seem to find it at the moment...
