Paola Gianturco and her eleven-year-old granddaughter documented the work of fifteen girl-led nonprofit groups in thirteen countries in Asia and Central Asia, North and Latin America, the Middle East, Africa and Oceania. They interviewed and photographed 90 girls. Groups of activist girls age 10-18 are transforming our world: improving education, health, equality and the environment; stopping child marriage, domestic violence, trafficking and war. Wonder Girls Changing Our World is a call to action to help these girls accomplish their important work.
