Flossie Crums is a bit messy, loves dressing up and sometimes finds her brother very annoying. She loves to bake and to play with the fairies that live in her garden (their kingdom is in a big chestnut tree). One magical day, Flossie is invited to make fairy cakes for Fairy Queen Rosie's big birthday celebrations. With so much baking to do how will she ever get them made in time? And will they be good enough to bring a smile to Queen Rosie's face?
