«The Princess and the Goblin & The Princess and Curdie (With Original Illustrations)» by George MacDonald

The Princess and the Goblin and its sequel quietly suggest in every incident ideas of courage and honor. Both the books start out as normal fairy tales, but slowly become stranger, and they contain layers of symbolism similar to that of Lewis Carroll's work. Eight-year-old Princess Irene lives a lonely life in a castle in a wild, desolate, mountainous kingdom, with only her nursemaid "Lootie" for company. Her father the king is normally absent, and her mother is dead. Unknown to her, the nearby mines are inhabited by a race of goblins, long banished from the kingdom and now anxious to take revenge on their human neighbors. One rainy day, the princess explores the castle and discovers a beautiful, mysterious lady, who identifies herself as Irene's namesake and great-great-grandmother. The adventure continues with Princess Irene and Curdie a year or two older. They must overthrow a set of corrupt ministers who are poisoning Irene's father, the king. Irene's grandmother also reappears and gives Curdie a strange gift. A monster called Lina aids his quest.

George MacDonald (1824-1905) was a Scottish author, poet, and Christian minister. He was a pioneering figure in the field of fantasy literature and the mentor of fellow writer Lewis Carroll. His writings have been cited as a major literary influence by many notable authors including W. H. Auden, C. S. Lewis, J. R. R. Tolkien, Walter de la Mare, E. Nesbit and Madeleine L'Engle. G. K. Chesterton cited The Princess and the Goblin as a book that had "made a difference to my whole existence".
