Hogfather

It's the night before Hogswatch. And it's too quiet.
There's snow, there're robins, there're trees covered with decorations, but there's a notable lack of the big fat man who delivers the toys . . .
He's gone.
Susan the governess has got to find him before morning, otherwise the sun won't rise. And unfortunately her only helpers are a raven with an eyeball fixation, the Death of Rats and an oh god of hangovers.
Worse still, someone is coming down the chimney. This time he's carrying a sack instead of a scythe, but there's something regrettably familiar . . .
Ho. Ho. Ho.
It's true what they say.
'You'd better watch out . . .'
