As nonsensical as Pratchett’s Discworld books may seem, they often make a great deal of sense. Hogfather pokes fun at old gods, evolving gods, power, and belief systems. There’s even an “oh god,” as in “oh god I’m gonna be sick.”
The Hogfather is Discworld’s version of Santa Claus, and things go very, very far astray forcing Death to step in and try to put things right, while his granddaughter tries to behave like a normal person.
And I always enjoy reading Death trying to understand humans, and trying to behave as though he’s human when needed. Usually with very confusing results for the humans he encounters. Think Nightmare Before Christmas when Jack Skellington tries to introduce Christmas joy to Halloween Town.
