Twig was just a plain, ordinary little girl who lived on the fourth floor of a "high sort of house" in the city. The back yard behind that house was Twig's little world. It was a bare little world, with nothing but a dandelion and a stream of drainpipe water to make it beautiful; with nobody but Old Boy, the ice-wagon horse, Old Girl, the cat, and the Sparrows, to keep Twig company.
But one day, out in the alley, Twig found an empty tomato can, with pictures of bright red tomatoes all round it. When it was upside down, it looked like a pretty little house, just the right size for a fairy Twig stood it upside down next to the dandelion, not far from the stream. And this is the story of what happened in and around that little house one Saturday afternoon.
A story full of magic, full of fun, full of fantasy interwoven with reality, and full of the kind of tenderness which belongs most particularly to the very young. A story both boys and girls will love.
