On the day the world ends . . .

. . . Mau is on his way home from the Boys' Island. Soon he will be a man. And then the wave comes - a huge wave, dragging black night behind it and bringing a schooner which sails over and through the island rainforest. The village has gone. The Nation as it was has gone. Now there's just Mau, who wears barely anything, a trouserman girl who wears far too much, and an awful lot of big misunderstandings . . .

Wise, witty and filled with Terry Pratchett's inimitable comic satire, this is a terrific adventure that - quite literally - turns the world upside down.
