(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."

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.
