Can Doctor Proctor, Nilly, and Lisa save Christmas in this new fart-tastically funny adventure from worldwide bestselling author Jo Nesbø? When the king of Norway sells the rights to Christmas to Mr Thrane, it looks like the holidays aren't going to be very merry. Mr Thrane says that the only people who can celebrate are those who buy 10,000 crowns worth of presents from his department store. For anyone who doesn't - or can't - spend that much, it's no tree, no presents, no carols, and no Christmas pudding. Doctor Proctor, Nilly, and Lisa aren't going to take this sitting down! They're going to find Santa and save Christmas. All they need is a sleigh, flying reindeer, some time travel soap, and, of course, some fart powder! PRAISE for the Doctor Proctor's Fart Powder series: 'This terrific book will make you laugh, and cherish your friends' - James Patterson 'plenty of toilet humour, and general silliness that kids love' - The Bookseller 'wickedly entertaining' - The Big Issue 'Lashings of silliness, quirkiness, self-deprecating humour, and a rollicking plot…' - TheBookbag.co.uk 'Fuelled by farts, this is fast-paced and a delightfully ridiculous adventure' - Julia Eccleshare on lovereading4kids.co.uk 'A superb mix of bizarre and wacky with a little bit of off-beat thrown in. Reminiscent of Roald Dahl it has all the elements to keep children hooked...' - Waterstones
