The Last Hero.

By Terry Pratchett, Illustrated by Paul Kidby

Synopsis:
Cohen the Barbarian and his Silver Horde, fed up of the good life, are going to take on the Disc's gods... The Patrician of Ankh-Morpork, aided, abetted and annoyed by the faculty of the Unseen University, doesn't think it's such a good idea, and tries to head them off at the pass, as it were, by inventing space travel.

Review:
Oh so pretty... The story itself is fairly straightforward, compared to your average Pratchett plot (Tis funny, nevertheless), but for once (speaking generally, not just of Discworld, by the way) the illustrations really add to the story, rather than just being a distraction. The Librarian continues to steal scenes, Rincewind is showing worrying signs of deviousness, and everyone in the world should buy this book because it's just so damn pretty. Of course, it doesn't really fit in with my nice neat row of battered Discworld paperbacks, but then neither will The Amazing Maurice and his Educated Rodents, just as soon as I get around to buying that... (Update: It's OK, I managed to restrain myself until it came out in paperback)
