OOK!
The Great A'Tuin finally reached its destination and Discworld ceased to exist. As it was destined. As it should. Without the Library of books yet to be written or the Librarian to find them, we can now only see into its past. And it remains wonderful.
In this day and age I recommend that, if you read no other work, read Jingo - not his best but supremely relevant. But don't just do that. Read them all, even the non-Discworld works.
