Our top picks at a glance

  • Best place to start (ages 7-12): The 13-Storey Treehouse by Andy Griffiths and Terry Denton. Andy and Terry live in a treehouse with a tank of man-eating sharks, when they should be writing a book.
  • Best for young detectives (ages 7-8): The 52-Storey Treehouse by Andy Griffiths and Terry Denton. Their publisher Mr Big Nose has gone missing. Our LoveReading4Kids review praises its "absurd, anarchic, keep-them-reading comedy adventures".
  • Best for time-travel fans (ages 7-10): The 65-Storey Treehouse by Andy Griffiths and Terry Denton. Terry forgot the building permit, so they invent a time machine and land 650 million years in the past.
  • Best for budding film-makers (ages 7-12): The 78-Storey Treehouse by Andy Griffiths and Terry Denton. The treehouse is being made into a film, and Andy loses his role to a gibbon.
  • Best for joke lovers (ages 7-10): The 104-Storey Treehouse by Andy Griffiths and Terry Denton. Andy has toothache and cannot laugh, with a book deadline looming. Our LoveReading4Kids review says "There are few books that reach such levels of absurd comedy and adventure".

Andy Griffiths on where the idea came from

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."
