Stories for girls in this age-group are awash with sparkles and twinkles and pinkness, but this story is refreshingly different - the tree-witch that looks over Natasha's garden threatens to steal a human baby in revenge for her own lost child, and the underground land of fairies is alluring but sinister. There's ancient wisdom, too, in the shape of the Romany grandmother of Natasha's new friend, Jamie, and the lovely detail of fairy rings growing up through the carpet of a newly-built house. This book lives up to the promise of its enchanting cover - and all ends well for Natasha and for the stone fairy, Pillywiggins.
