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 fill it. Together with Fortnight the Friday knight and Fossfiddle the wizard, Ralph sets out to defeat the fearsome fire-breathers.

But there's a teeny weeny surprise in store . . .

Fourteen fantastically funny stories from master storyteller Sir Terry Pratchett, full of time travel and tortoises, monsters and mayhem!
