In the neighborhoods of Philadelphia, a secret had been whispered about for years. The agency watching over the city’s children was heavy-handed, people said. It was easy for a family to lose its children into foster care, it was rumored. Carolyn Hill heard the stories, then she became one of those people. The mother of five had taken in her two nieces in 2011, and a year later, she watched them walk out of her house with a social worker, right in the middle of the family's dinner. “I just bought their Easter dresses,” Hill said. They had just begun to understand what it felt like to be loved and safe. Before the girls moved into Hill's home, they didn’t know they were sisters, separated into different foster homes and bounced around.
