Imagine a United States in which registries and detainment camps for Muslim Americans are a reality. This is the world of fifteen-year-old Sarah-Mary Williams of Hannibal, Missouri. Sarah-Mary, who has strong opinions on almost everything, isn't concerned with the internments, as she doesn't know any Muslims. She assumes that everything she reads and sees in the news is true, and that these plans are better for everyone's safety. Then she meets Sadaf, a fugitive escaping to Canada. Should she turn her in... or help her?
