Selma Lagerlöf story of Nils, the bad boy that gets turned into a tiny elf, and of his adventures in animal-land, has become a real fairy classic. Seldom has such intricate weaving and interweaving of fact and fancy, history and tradition, fairy lore and nature craft, been accomplished so deftly... the style is simple and natural, the story whimsical and rich in delicate humor. (New York Sun) Selma Lagerlöf is the greatest imaginative genius in modern literature. Few men or women in the world have ever had the right to write fairy stories, but Selma Lagerlöf in one of them.
