Danlo Ree lives in a world within walls, in a society of telepaths. It is an efficient society, peaceful and pure. The Cleansings are sure of that.
Danlo thinks bad thoughts sometimes, about his wife, and the Cleansings....but he pushes them away. He must survive here, for outside the walls lurks nothing but chaos and radiation and danger.
Now, something incredible has happened. And Danlo Ree has discovered that there is something else outside the walls...
Life.
