MIGHTY BATTLES! REVOLUTION! DEATH! WAR! (AND HIS SONS TERROR AND PANIC, AND DAUGHTER CLANCY). The oldest and most inscrutable empire on the Discworld is in turmoil, brought about by the revolutionary treatise What I did on My Holidays. Workers are uniting, with nothing to lose but their water buffaloes. Warlords are struggling for power. War (and Clancy) are spreading throughout the ancient cities. And all that stands in the way of terrible doom for everyone is: Rincewind the Wizard, who can’t even spell the word ‘wizard’… Cohen the barbarian hero, five foot tall in his surgical sandals, who has had a lifetime’s experience of not dying… …and a very special butterfly.

‘Anything you do in the past changes the future. The tiniest little actions have huge consequences. You might tread on an ant now and it might entirely prevent someone from being born in the future.’ There’s nothing like the issue of evolution to get under the skin of academics. Even if their field of expertise is magic rather than biology. With the best and most interfering minds of Unseen University somehow left in charge at a critical evolutionary turning point, the Discworld’s last continent needs a saviour… Who is this hero striding across the red desert? Sheep shearer, beer drinker, bush ranger, and someone who’ll even eat a Meat Pie Floater when he’s sober. In fact, it’s Rincewind, a wizard so inept he can’t even spell wizard. He’s the only hero left. Still…no worries, eh?
