Mercedes Lackey is usually considered adult fantasy, but many of her fairy tale retellings are appropriate and interesting for young adult readers. I especially like some of her books, because they place fairy tales in a variety historical backdrops. The Gates of Sleep places the story of Sleeping Beauty in a pre-Raphaelite home of artists and free thinkers. Part of the evil being fought is industrialization and pollution of the earth. This is an entertaining and interesting presentation of fairy tale and some history.
