In the novel Among the Hidden by Margaret Peterson Haddix, Luke has been sheltered by his family and, unlike most third children, allowed to be outside among the trees on the property which shelter the knowledge of his presence from outsiders. However, when the government begins to cut down all the trees which hide the property and now expose any attempt by Luke to be outside in the freedom he was accustomed to, Luke is more confined than ever before to hide his existence. When his father's pigs are destroyed or sold by the government, the family is left more destitute than ever and can't handle the burden of a third mouth to feed. Luke begins to see the differences between his old world as a third child where he is hidden but allowed many freedoms and this new outside world where everything is regulated and controlled by the government. Even his father's attempts to grow food hydroponically with Luke's advocacy results in the project being forbidden. When Luke's new friend tries to get him to go to a rally to get the government to change, Luke knows that it is too dangerous and tries to get her to not go. Finally, Luke knows that he must make his own way in the world among the hidden children and figure out what is best for him by himself.
