On the other side of the wall there is a dark secret. And the devil. And the Moon Man. And the Motherland doesn't want anyone to kw. But Standish Treadwell, who has different-colored eyes, who can't read, can't write, Standish Treadwell isn't bright, sees things differently than the rest of the train-track thinkers. So when Standish and his only friend and neighbor, Hector, make their way to the other side of the wall, they see what the Motherland has been hiding. And it's big.
