Dawn and her best friend Amber are students at Stillwater School, an experimental academy that's the laughingstock of Atlanta. When Ms. Ella arrives to teach the eighth grade, she shakes up the school with her radical ideas and violent discipline, building an enthusiastic following and even winning the loyalty of rebellious Dawn.

The imprint she leaves on her students is both profound and damaging, long after scandal shuts down the school and leads to Ms. Ella's arrest. Dawn pursues a destructive path into Ms. Ella's family, while Amber embraces a solitary, bookish life. Years later, after Dawn's mysterious death, Amber sets off to find her estranged former teacher. In the process, she uncovers a shocking story of narcissism, art, betrayal, and murder.
