Quick Assessment

Sephy, a pregnant teenager, lives in a society where racial prejudice threatens her unborn mixed-race child, and she is haunted by the hanging of the baby's father for terrorism. Her dead partner's brother blames her and plans revenge, which drives a tense story about grief, despair, and violence. Expect frequent racist hostility, threats to life, and emotionally heavy scenes, which make it best suited to older teens who can discuss these themes with a parent.
