Hogfather is a fantasy novel written by Terry Pratchett, part of his popular Discworld series. In this humorous and satirical Christmas tale, the Hogfather (Discworld's equivalent of Santa Claus) goes missing, and Death takes on the task of delivering presents to children. As Death tries to understand the meaning of Hogswatch (Discworld's version of Christmas), chaos ensues, and the boundaries between reality and fantasy blur. Pratchett's witty writing and clever observations make Hogfather a delightful and thought-provoking read for fans of fantasy and holiday-themed stories.
