I recently read Coraline by Neil Gaiman
Coraline just moved into a new house(which she has to share it with some odd people).Even then, Coraline still had nothing to do.But one day,she discovered a door blocked by bricks.when she found the key,she was able to go in.At the end of the tunnel,she saw what looked like her parents,except they had buttons for eyes.They cooked way better meals,and a much nicer house. All she had to to stay was replace her eyes with buttons.She didn't want to.So they striked a deal.If she could find the souls of her parents and the soul of three other children's,she could leave freely.
She did,in fact,find them and she was set free.
