A real witch never casually steps out of her body, leaving it empty. Eleven-year-old Tiffany does. And there's something just waiting for a handy body to take over. Something ancient and horrible, which can't die...Wise, witty and wonderful, "A Hat Full of Sky" is Terry Pratchett's second novel about Tiffany and the "Wee Free Men" - the rowdiest, toughest, smelliest bunch of fairies ever. They'll fight anything. And even they might not be enough to save Tiffany...
