The Enchanted Island of Yew

Three young girls wander into an enchanted forest at meet a fairy woman, who is bored with her perfect, immortal life. She convinces them to turn her into a human and decides to become a prince because boys have more fun. His/her new existence exploring the surrounding kingdoms is fast and adventurous from the get-go. What unfolds in an interesting story of problems solved by a woman's mind in the luxury of a man's body. 'The Enchanted Island of Yew' (1903) was written by L.

This story clearly comes from the same imagination, however, with the added bonus of some interesting gender-bender elements.
