As the author of the hugely popular Isadora Moon series, Harriet has captivated millions of young readers around the world. Translated into 42 languages, the series blends everyday emotions with magical adventures, helping children build confidence in reading while exploring themes of identity, friendship, and self-expression.

Now, Harriet is inviting readers to explore a new world with The Diary of Wiska Wildflower. Aimed at slightly older readers, the series supports the transition to more advanced fiction through a playful diary format filled with full-colour illustrations, notes and letters. Wiska, a tiny wiskling with a big heart, navigates friendships and challenges at Inkcap’s Academy. The story encourages empathy, creativity, and resilience.  

Harriet’s storytelling has also leapt from the page to the screen. Emerald, a new animated TV show based on the world of Isadora Moon, launched on Sky TV on 1 September. Created with Kelebek Media, the series follows a mermaid princess as she faces unexpected challenges and learns to embrace change. It offers children a fresh way to engage with Harriet’s themes through visual storytelling.Â
