Hi folks - I'm looking for a LGB for a friend. She's given me a little bit of plot info (as much as she could recall), but doesn't know the title. I was curious if anyone might know the title of this book. The book begins with a child (we think a girl) who finds a magical stone with a keyhole in it. When a key is inserted and turned, the child is carried off to a magical fairy land. That's all we know - sorry - wish I knew more. If anyone has any clues, I'd be very appreciative. Thanks!
