Clare and Zari are best friends. They write music together, go everywhere together, and they know everything about the other. At least they did before Zari started dating Dion. The more Zari falls for Dion, the less she has time for anything else. At first, Clare chalks it up to a new and exciting relationship, and she tries to be happy for her friend despite her loneliness. When Zari starts to show up to school with half-hidden bruises, Clare knows there's something darker about this relationship that has to be stopped.
