Julia Donaldson Unveils Third Gruffalo Book, 'Gruffalo Granny,' Out 10 September 2026

Donaldson ties the revival to early-reading efforts led by the National Literacy Trust.

Overview

  • The author confirmed the title on BBC Radio 4’s Today programme as Macmillan set the publication date.
  • Long-time collaborator Axel Scheffler will illustrate the story, which introduces Gruffalo Granny and reunites Mouse, Fox, Snake and Owl.
  • A first look at the new character was projected in central London and Glasgow, including on the British Library, showing grey fur, red prickles, green eyes, a walking stick and a knapsack.
  • Donaldson said the National Literacy Trust’s Early Words Matter programme spurred her to finish the idea after more than two decades since the last sequel.
  • The book will be released in hardback and as an audiobook, with the series’ earlier titles having sold over 18 million copies across 115 languages and dialects.
