Discworld — Terry Pratchett

Terry Pratchett's 41-novel Discworld series is the greatest comic fantasy achievement in English literature — and considerably more than comedy. Pratchett used his flat world balanced on four elephants standing on a giant turtle as a laboratory for satirising every aspect of human society: politics, religion, journalism, economics, war, gender, and death. His wit and his genuine humanity make Discworld one of fiction's great achievements in any genre.
