Find out more about this popular series in this special section; surreal, kid-pleasing comic adventures set in an ever-growing treehouse!

The Treehouse series is the creation of best mates Andy Griffiths and Terry Denton. Andy is Australia's number one children's author and a passionate advocate for literacy. Terry is also a best-selling author/illustrator working on a range of titles including the Horrible Science series. They both live in Melbourne, Australia.

Andy told us a little about the Treehouse series and what inspired him to create it? "I’ve been lucky enough to work with Terry, the illustrator, for twenty years now and together we love entertaining each other and seeing just how far we can push our humour. The treehouse series grew out of this process of constant experimentation and play. And, I guess, my love of Enid Blyton’s ‘Faraway Tree’ books were probably responsible for the idea of a magical tree filled with unpredictable things and people."
