Twelve-year-old Shayla is allergic to trouble. All she wants to do is to follow the rules. (Oh, and she'd also like to make it through seventh grade with her best friendships intact, learn to run track, and have a cute boy see past her giant forehead.) But in junior high, it's like all the rules have changed. Now she's suddenly questioning who her best friends are and some people at school are saying she's not black enough. Wait, what? Shay's sister, Hana, is involved in Black Lives Matter, but Shay doesn't think that's for her. After experiencing a powerful protest, though, Shay decides some rules are worth breaking. She starts wearing an armband to school in support of the Black Lives movement. Soon everyone is taking sides. And she is given an ultimatum.
