The Princess and Curdie Curdie by George Macdonald, Classics, Action & Adventure

In the years since the end of The Princess and the Goblin, Curdie has managed to convince himself that the supernatural events of that tale were products of his wild imagination. But then events draw him back to Grandmother -- that is, Mother Wotherwop, Princess Irene's great-great-great-grandmother, the Lady of the Silver Moon -- and Curdie regains his innocence and his faith. The Lady sends him on a quest to help the king and princess confound their enemies -- and save the kingdom!
