Andy Griffiths: Australian author of the Treehouse series (with Terry Denton) — anarchic, illustration-heavy, gag-saturated chapter books that anchor the 6–10 reluctant-reader shelf in UK and Australia.

Andy Griffiths is an Australian author born in 1961, best known as the writer of the Treehouse series, beginning with The 13-Storey Treehouse (2011) and continuing in 13-storey increments, illustrated throughout by Terry Denton. The series is an exuberant, gag-saturated, illustration-heavy chapter-book franchise that has become one of the dominant reluctant-reader properties in UK and Australian publishing for ages 6–10. Griffiths' earlier Just Annoying!, Just Tricking! and Just Stupid! short-story collections established his voice: anarchic, gross-out, gleefully silly. The Treehouse books interleave prose with comic panels, single-page gags and absurd inventions on every spread. A reliable read-aloud engine.
