The 13-Storey Treehouse Pack x 4 Pack by Andy Griffifths (author) and Terry Denton (illustrator)

Lucky enough to have a treehouse? That’s cool – but is yours like this? It has more treats and surprises than Willy Wonka’s chocolate factory. And with every book you read, it GROWS! It’s got a giant catapult, a detective agency and a tank of man-eating sharks. There’s a skate park, an ice cream parlour and a ninja snail training academy. There’s even a life-size snakes and ladders game with real snakes! Oh – and did we mention that each book has thirteen cool stories packed with laughs and cartoons? Come on up!

• The first four books in this hugely popular series

• Laugh-out-loud short stories plus funny cartoons

• Full of imagination, humour and topsy-turvy fun

• Winner of the ABIA Book of the Year Award 2015

• A cheeky treat for fans of Roald Dahl and Mr Gum
