The Treehouse series was the first book series I ever read. I never really liked reading but when I read your books I started to like to read!

I have students in my class queuing up to read your books. I can see a change in the children already, and can see that they are starting to see how enjoyable reading can be.

It is difficult to fully express the gratitude that I feel as an educator, for the wonderful contribution that your literature has made to students of all ages. In my case it is a thrill to finally see them enjoying the wonderful experience of reading independently.

Your books are my students absolute FAVOURITE! They are simple and crazy—when they read your books they laugh, read and feel confident in their ability. THANK YOU for helping me help my students to feel successful & happy.

Thank you for making the best book that inspires kids to like reading. I liked this book because it had a lot of action.

I LOVE your books because there’s always crazy stuff happening!

The stories and adventures are so funny to read combined with the drawings, it makes me laugh. Thank you for all the nice books!

Anarchic absurdity at its best

I used to not like to read but from the first sentence of the 13 Storey Treehouse I knew I would like it.

As a former high school teacher and librarian, I truly appreciate your books. They are perfect for reluctant readers.

Part chapter book, part graphic novel, all humour and playfulness, the Adventures Unlimited series will delight existing Griffiths devotees, and win new ones.

Thank you for making me love reading. You really changed my life with your book.

What I like about the books (aside from the absurdity of them) is that they are subliminally designed to inspire creativity in children.

Our son read The 13-Storey Treehouse and was hooked. From there, he’s read EVERYTHING he can get his hands on. You have turned his life around, given him confidence and opened doors for him that until recently were firmly shut.

They are marvellously silly and wonderfully irreverent (very important in children’s books) and are full of just the right amount of heart.

The kind of book I would have loved as a kid.

Brilliant series! Start at the beginning and work through them all. Laugh-out-loud funny

I didn’t really like reading last term, but now I love it!

If it wasn’t for you I would not be a confident reader.

I have not really been interested in reading until I came to see you. I now can’t put your books down! I have all of them!

Easy-to-read, visually exciting and wonderfully entertaining, the pace is fast and the fun never stops. Simply brilliant and guaranteed to get even the most reluctant readers begging for more!

The 78-Storey Treehouse is amazingly funny. It’s full of laughs, action and adventure. A perfect combination!!!

I love your books because they are very interesting and very funny especially you ,Terry and Jill. You are a great writer.

If you know any young fans of wild, goofy humour, they absolutely must check out The 117-Story Treehouse

Your books have unlocked my son’s love for reading. These Treehouse books are something special, so thank you!
