And you guessed it, that old roo-de-lally Mr Gum and his trusty sidekick Billy William the Third have something to do with it. But … our favourite heroes Polly and Friday and the gingerbread biscuit Alan Taylor (only 15.24 cm tall) are determined to save the town (sigh of relief). Mr Gum and thePower Crystals is the fourth book in the internationally best-selling series by Andy Stanton, which has won everything from the Blue Peter Book Award (twice) to the Roald Dahl Funny Prize and the Red House Children’s Book Award.
