Where is the big jolly fat man? Why is Death creeping down chimneys and trying to say Ho Ho Ho? The darkest night of the year is getting a lot darker... Susan the gothic governess has got to sort it out by morning, otherwise there won't be a morning. Ever again... The 20th Discworld novel is a festive feast of darkness and Death (but with jolly robins and tinsel too). As they say: You'd better watch out.
