The Great A'Tuinment
Discworld: A round, flat world which rides on the back of four enormous elephants, who in turn ride on the back of the eternal cosmic turtle known as Great A'Tuin, who drifts through space in a methodical meandering towards some unknown destination…or just wherever he feels like that millenium.
But something has been wrong with A'Tuin's course. He is headed in a new direction, and the world is starting to notice. Storms, earthquakes, changes in temperature, and a general feeling of "Just what the hell is going on here?" abound.
What is causing this disturbance in the mind of the star-turtle? It's up to our heroes, The Told Ones, to find out!
