Esther* grew up in rural Ghana, hours from the waters of Lake Volta. But when a woman approached her parents, claiming there was a family near the lake who would send their daughter to school, they allowed the woman to take her. The promise of an education was a lie. Little Esther was enslaved when she was just six years old.

Last week, an elderly man’s moment of desperation catalyzed rescue for 42 people. Kasi’s image has awakened thousands to the reality of modern slavery around the world—and his passion has fueled us to keep up the fight against it.
