Men at Arms (Discworld, 15)

Another wild romp through Discworld! Corporal Carrot, a young dwarf, is newly in charge of the recruits guarding Ankh-Morpork. Edward, the 37th Lord d'Eath, has just discovered that Ankh-Morpork, kingless for generations, has a sovereign ruler, who must be convinced that he is, in fact, the King. The fate of Ankh-Morpork rides on a young man's courage, an ancient sword's magic, and a three-legged poodle's bladder.
