Every night, before Sylvia goes to sleep, she whispers a magic spell to the rhyme-elves. In the morning her Wonder Book is filled with beautiful pictures and poems of her adventures and the extraordinary stories she has heard. There is nothing Sylvia loves more than stories; so every day she asks her mother, the old woodsman and even her fairy friend Sister-in-the-Bushes to tell them to her. They weave magical stories of clever princesses, far-away kingdoms, courageous knights, kind children and graceful fairies. During the day, Sylvia also has her own adventures: planting a fairy tree, meeting St Nicholas and venturing into the deep woods. But as she comes closer to her special seventh birthday, there is one extraordinary adventure left. This enchanting collection of tales, charmingly told by Isabel Wyatt, takes us through the highlights of the year as Sylvia and her friends celebrate festivals and birthdays.
