Oxford Children’s today announced the upcoming launch of the Isadora Moon TV tie-in publishing range, based on the smash-hit animated series created by Kelebek Media, based on the original world created in a series of books by Harriet Muncaster. Lou John from Oxford Children’s acquired world rights from Deborah Thorpe, Founder & Creative Director of Kelebek Media.

Publishing in May 2026, the range will debut with four picture books and four activity books for ages 4–7, followed by fourteen additional titles including early readers, in September 2026. With 32 books planned across two years, this marks an exciting expansion of the Isadora Moon universe.

Lou John, Head of Children’s and Primary IP at Oxford Children’s, said: “The success of Isadora Moon is down to its exceptional characters and rich storytelling. As well as our core publishing, we’re now proud to be expanding the reach of this key brand by bringing these gloriously entertaining TV tie-in stories, activity books and fiction to an even wider global audience.”

As Oxford Children’s celebrate ten sparkling years of Isadora Moon, with over 6.4 million copies sold worldwide, they are delighted to collaborate with Kelebek Media and build on the popularity of the Isadora Moon TV series, currently airing on Sky Kids in the UK, Warners Bros Discovery in the US and on broadcasters around the world.

The range features stunning artwork from the TV series across picture books, activity titles, early readers, and older-reader formats. Young fans can revisit beloved episodes through richly illustrated picture books or get creative with fun activity books, including a Search and Find book and a charming Fairy–Vampire flip book, filled with puzzles, games, colouring pages, sticker sheets, and other activities.

Whether fans are meeting Isadora for the first time through the TV series, the new TV tie-in product range, or the bestselling original 5-7 core chapter books, Oxford Children’s are encouraging children to explore storytelling in fun and imaginative ways, mirroring the ambitions of the National Year of Reading. As it marks this milestone year, the TV tie-in programme range represents a bold step in expanding the world of Isadora Moon.

Deborah Thorpe, founder of Kelebek Media, said: “We’re very proud of our close collaboration with the fantastic team at Oxford Children’s to expand the hugely successful Isadora Moon publishing world. And we’re very grateful to Harriet for placing her trust in us. These books and activities extend the magic of Isadora beyond the animated series, inviting children to explore stories in playful accessible ways that spark imagination and nurture a lifelong love of reading.”

Harriet Muncaster, author and creator of the world of Isadora Moon said: “It’s super exciting to see Isadora in this new format which makes the Isadora Moon world accessible to even more readers! I love everything Kelebek Media have done to bring Isadora Moon to life in animation, and the animated version of Isadora is so cute! I love how they look on my bookshelf alongside my other books!”
