When Sarah Perry was 12, she saw a partial eclipse; she took it as a good omen for her and her mother, Crystal. But that moment of darkness foreshadowed a much larger one: two days later, Crystal was murdered in their home in rural Maine. It took 12 years to find the killer. In that time, Sarah rebuilt her life amid abandonment, police interrogations and the exacting toll of trauma. She dreamed of a trial, but when the day came, it brought no closure. It was not her mother’s death she wanted to understand, but her life. She began her own investigation, one that drew her back to Maine, deep into the darkness of a small American town.
