Once upon a time, in a land you only think you know, lived a little girl and her mother . . . or the woman she thought was her mother.

Every day, when the little girl played in her pretty garden, she grew more curious about what lay on the other side of the garden wall . . . a rather enormous garden wall.

And every year, as she grew older, things seemed weirder and weirder, until the day she finally climbed to the top of the wall and looked over into the mines and desert beyond.
