The Princess and the Goblin | George MacDonald

Princess Irene's discovery of a secret stair to the top turret of the castle leads to a wonderful revelation. At the same time, the miner's son Curdie overhears a fiendish plot by the goblins who live below the mountain. But it will take all their wit and courage, and the help of Irene's magic ring, to make sense of their separate knowledge and foil the goblins' schemes.
