Sadie is a 13-year-old girl of mixed Black and white race. She is Bird’s only friend. When she was 11, Family Services removed Sadie from her parents’ custody because her mother, Erika’s, journalistic investigations into other child removals constituted a violation of PACT. Sadie has strong opinions and is confrontational. When Bird meets her in sixth grade, she has already been with two foster families, having earned a reputation as a troublemaker. Sadie views her mother as a hero for standing up against PACT, and she introduces Bird to Margaret’s role in the resistance. With the help of Carina, the Cambridge librarian, Sadie runs away from her foster family to find her parents, but her search turns up cold. Through Sadie, the novel illustrates the very real impact of prioritizing patriotism above free speech in this imagined world. Additionally, Sadie’s insistence on finding her parents calls into question the motives of the authorities who separated them, and it suggests that the forced removal of children is harmful as opposed to protective.
