Gwendy's Button Box is not one of King's usual horror stories; it's lighter, and more toned-down. Still, it was an enjoyable afternoon read.
When Gwendy is twelve years old, she meets a man who offers her a mahogany box covered with eight colored buttons. The man tells Gwendy that he's been watching her and has decided she is "set solidly on her feet" and is worthy enough to keep the button box, for now. He shows her how to make the box release a tiny piece of chocolate and explains the importance of the buttons, especially the "everything" button, and then he disappears.
