Through conversations with her grandma and their shared love of books, Justice learns about important women and men throughout history who changed the world: Ella Baker, Shirley Chisholm, Charles Hamilton Houston, Dr. Wangari Maathai, Paul Robeson, and Ida B. Wells. Justice learns how each leader was a champion for advancing justice and improving the world, and she dreams of becoming a change maker, too--"Miss Freedom Fighter, Esquire," a superhero with a law degree.
