Ebony Thomas is the author of “The Dark Fantastic: Race and the Imagination from Harry Potter to the Hunger Games.” For her the most important word in that title is "imagination." She believes that without imagination we can't change the world because we can't see it. We can't daydream a better world into existence. It's why she's always identified with another literary daydreamer — Anne of Green Gables.

A girl, a horse, and a magical sword save a kingdom in Robin McKinley's young adult classic, "The Blue Sword" — a book beloved by women of all ages. "Hild" author Nikola Griffith explains why.
