Letitia Hopkins has always been curious about the peculiar green door in her Aunt Peggy's cheese room. But whenever she asks about it, she is always forbidden to open it or go through it. And the door is always locked.
But one day, she finds a small black key on a green ribbon. And when she is left alone in the house, she cannot resist the temptation to try the door. Immediately Letitia finds herself in a strange, unfamiliar world full of wild animals, hostile natives, and a frontier life of hardship and hard work in the company of her pioneer ancestors. But how is she to find her way back to her own time?
A splendid children's classic which still delights today's young generation.
