Book Review: Gwendy's Button Box

This one was over too soon. King and Chizmar (although it must have been King because he started the story) tell a story about a box that is the perfect blend of mystery and power. You want to press the buttons and find out what happens, but you're also afraid of it -- although I want more detail. The central character is believable and grows up convincingly through her interactions with others -- although I want more detail. The whole story is an entertaining contrivance, without much weight to it, like the button box itself. It's also well-crafted -- I had no idea it was co-written till it I found out through an interview at the end. If this is the product of King co-writing, then he should co-write more.
