^I've read that too. The darker origins of fairy tales are pretty interesting to me. The Fae were not always cast in such a happy sparkly light. You had to leave tithes and stuff so they wouldn't kill your crops!
Speaking of, I highly enjoyed the Sevenwaters series by Juliet Marillier. Some of it is a little too girl-must-rescue-boy-from-himself, but I like the characters.
