The eighth book in the Discworld collection but one of the best to start with, Guards! Guards! introduces the motley crew of the Night Watch and their captain Sam Vimes, not to mention Carrot, a human raised as a dwarf. The story is set entirely in Ankh-Morpork, giving us a very good view of the city at "street level" as the Watch try to come to grips with the new balance of power now that dragons turn out to be real.
