When Em Morales's older sister was raped, her world was turned upside down. Her family thought her sister was going to get real justice when the jury found the rapist guilty, but the judges sentences the rapist to no prison time, shattering any sense of hope. Em is sick with rage and guilt, but she finds a way to heal through writing poems about a fifteenth-century French noblewoman, Marguerite de Bressieux, who was legendary as an avenging knight for rape victims.
