Luke lives on a farm. He used to be able to play in the back yard, but that changed when the government cut down all the trees. Luke is an illegal third child, so he has to hide in the house. It has been like this since before he was born. The government only allows two children per family. Luke thinks he is the only third child. But that all changes when the people next door move in and he thinks he sees someone, after he watched everyone leave the house.
