Celebrating a decade of magic with Isadora Moon Day 2026

On Saturday 14 February, we marked a major milestone in truly enchanting style with Isadora Moon Day 2026, a nationwide celebration of 10 magical years of Harriet Muncaster’s much-loved half vampire, half fairy heroine.

In this National Year of Reading, the celebration also offered a wonderful opportunity to champion reading for pleasure in all its forms. We’re proud to encourage children to read in whatever format excites them most, helping them discover stories that spark imagination and create lasting connections.

Reading can have a transformative impact on young people’s development and wellbeing: it opens minds to new ideas, cultures, and perspectives, and provides joy, motivation, and comfort, especially in uncertain times.

At OUP, we strive to create content for all levels and abilities that encourages reflection and helps every reader feel inspired by what they’re discovering. Isadora Moon, with her charm, humour, and heartfelt adventures, continues to do exactly that.

 

The highlight of the celebratory weekend was our birthday event with Kibworth Books at the Sue Townsend Theatre in Leicester.

The 250-capacity event featured a read-along and draw-along with author Harriet Muncaster, audience interaction, and birthday-themed fun, followed by a signing session both at the theatre and later at Kibworth Bookshop.

The event is supported by a wider programme of appearances by Harriet Muncaster over the next few weeks, including the Stepping into Stories Festival with Paper Cat Bookshop in London, a virtual multi-school event with Read Holmfirth Bookshop, and an upcoming appearance at the Four Bears Festival in Reading on 14 March.

At the heart of the celebration was the publication of the Isadora Moon Has a Birthday 10th Anniversary edition, a beautiful hardback reedition of the first Isadora Moon book, published in 2016. With sprayed edges, a foil cover, bonus activities, and an exclusive new Pink Rabbit short story, the edition is a standout moment in our anniversary programme.

Isadora Moon Day was only the beginning, with many more moments to come throughout the year that will celebrate the 10th anniversary. With its joyful blend of reading, creativity, and celebration, Isadora Moon Day made for a perfect start to this National Year of Reading and an enchanting beginning to a landmark year for the much-loved series.
