Books with title Princess and the Pauper

Princess Irene lives in a castle in a wild and lonely mountainous region. One day she discovers a steep and winding stairway leading to a bewildering labyrinth of unused passages with closed doors - and a further stairway. What lies at the top? Can the ring the princess is given protect her against the lurking menace of the boglins from under the mountain?

Curdie was the son of Peter the miner. He lived with his father and mother in a cottage built on a mountain, and he worked with his father inside the mountain.A mountain is a strange and awful thing. In old times, without knowing so much of their strangeness and awfulness as we do, people were yet more afraid of mountains. But then somehow they had not come to see how beautiful they are as well as awful, and they hated them-and what people hate they must fear. Now that we have learned to look at them with admiration, perhaps we do not feel quite awe enough of them. To me they are beautiful terrors.
