The Princess and the Goblin: Illustrated - Jessie Willcox Smith

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 neighbours.
