Dragons at Crumbling Castle

Dragons have invaded Crumbling Castle, and all of King Arthur's knights are either on holiday or visiting their grannies. It's a disaster! Luckily, there's a spare suit of armour and a very small boy called Ralph who's willing to wear it. Full of time travel and tortoises, monsters and mayhem, here are fourteen fantastically funny stories from master storyteller, Sir Terry Pratchett.
