1965: Growing up in the well-to-do town of Round Hill, North Carolina, Ellie Hockley has chosen to spend her summer break as a volunteer helping to register Black voters. But as she follows her ideals fighting for the civil rights of the marginalized, her scandalized parents scorn her efforts, and her neighbors reveal their prejudices. 2010: Architect Kayla Carter and her husband designed a beautiful house for themselves in Round Hill’s new development, Shadow Ridge Estates. It was supposed to be a home where they could raise their three-year-old daughter and grow old together. Instead, it’s the place where Kayla’s husband died in an accident. And her neighbor, Ellie Hockley, is harboring long-buried secrets about the dark history of the land where her house was built.
