When Molly's father, a fisherman, brings home a tiny pony from the sea, Molly is sure that the creature must be magic. Pure white, with hooves of gold, the pony is too special to keep in captivity, but the townspeople--believing that the pony will bring them good luck--lock it in a cage and throw away the key. Now, Molly and her friend Peter must find a way to save the beautiful pony, and return him to his home in the sea. Helen Cresswell's engaging, simply written fantasy adventure is perfect for young independent readers.
