Hex

Hogfather is not quite peak Pratchett, but it's getting there. And, of course, even so it is better than most genre fiction by a margin. Hogfather beats you over the head with uncomfortable truths, while also having you giggle at Death trying to be jolly Father Christmas, because the cosmic bureaucrats sent out assassins against him. This is a slight problem because Hogfather is responsible for making the sun rise, naturally.
