Corporal Carrot is now in charge of the new recruits guarding Ankh-Morpork from barbarian tribes, miscellaneous marauders, unlicensed thieves, and other dangerous Discworld denizens. It’s a big job for an adopted dwarf keeping the likes of young coppers Lance-constable Cuddy (really a dwarf), Lance-constable Detritus (a troll), Lance-constable Angua (a woman... most of the time), and Corporal Nobbs (disqualified from the human race for shoving) in line.

Especially since someone in Ankh-Morpork has been getting dangerous ideas about crowns and legendary swords, and destiny—which points its crooked finger again when an ancient document reveals that Ankh-Morpork has a secret sovereign. What's more, Captain Sam Vimes is getting married and retiring from the Watch. For good. Which is a shame, because no one knows the streets of Ankh-Morpork or its criminal underworld better than him.

It’s the beginning of the most awesome epic encounter of all time (or at least all afternoon), in which the fate of a city—indeed of the universe itself!—depends on a young man’s courage, an ancient sword’s magic, and a three-legged poodle’s bladder.
