Good evening. Talking parrots in the rooftops? A giant cactus on the high street? Mosquitos so nasty that even their own friends don't like them?
Something's gone terribly wrong in Lamonic Bibber . . . and Mr Gum is nowhere to be found.
Yes, folks, Polly and Friday are facing their biggest challenge yet.
So strap yourselves in, cry `HI-HO-WEIRDY!' and get ready for an adventure so crazy your feet will melt with happiness!
And I'm not just saying that, I've actually seen it happen. HOORAY!
Mr Gum and the Secret Hideout is the eighth 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.
