Pratchett, Terry. Discworld series

Originally published: London :Victor Gollancz, 1996

What could more genuinely embody the spirit of Christmas (or Hogswatch, on the Discworld) than a Terry Pratchett book about the holiday season? Every secular Christmas tradition is included. But as this is the 21st Discworld novel, there are some unusual twists. This year the Auditors, who want people to stop believing in things that aren't real, have hired an assassin to eliminate the Hogfather. (You know him: red robe, white beard, says, "Ho, ho, ho!") Their evil plot will destroy the Discworld unless someone covers for him. So someone does. Well, at least Death tries. He wears the costume and rides the sleigh drawn by four jolly pigs: Gouger, Tusker, Rooter, and Snouter. He even comes down chimneys. But as fans of other Pratchett stories about Death (Mort, Reaper Man, and Soul Music) know, he takes things literally. He gives children whatever they wish for and appears in person at Crumley's in The Maul
