Pillywiggins And The Tree Witch

When Natasha moves to a new house she discovers a statue of a fairy in her garden beneath a huge fir tree which Natasha is sure is a witch. With the help of a local boy she learns that fairies stole the witch's baby and in revenge she turned a fairy to stone. Natasha realises the only way to free the stone fairy Pillywiggins is to go to Fairy Land herself and rescue the witch's baby.
