A charming story of a beautifully brave goose from Judith Kerr, the creator of children's classics The Tiger Who Came To Tea and the ever-popular Mog series.

Meanwhile, the villagers try to solve the problem of the empty pond, and only little Millie Buswell seems aware that its inhabitants are missing too! Will she ever see her favourite goose again?
