IT'S THE NIGHT BEFORE HOGSWATCH AND IT'S TOO QUIET. 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...

Sir Terry Pratchett is a publishing phenomenon. Among his many prizes and citations are the WORLD FANTASY LIFE ACHIEVEMENT AWARD, the CARNEGIE MEDAL, the BSFA AWARD, eight honorary doctorates and, of course, a knighthood. In 2012, he won a BAFTA for his documentary on the subject of assisted suicide, 'Terry Pratchett: Choosing to Die'. He is the author of 50 bestselling books but is best known for the globally renowned Discworld series. The first Discworld novel, THE COLOUR OF MAGIC, was published in 1983, and the series is still going strong almost three decades later. Four Discworld novels -HOGFATHER, GOING POSTAL, THE COLOUR OF MAGIC and THE LIGHT FANTASTIC - have been adapted for television, with more to follow. His books have sold approximately 75 million copies worldwide (but who's counting?), and been translated into 37 languages. Terry Pratchett lives near Salisbury in Wiltshire.
