The most mysterious is that of Sara Harrison Shea, who was found murdered in the field behind her house in 1908, a few short months after the tragic death of her daughter, Gertie, drove her mad. People say that Sara's ghost still walks after dark, and some leave offerings on their doorstep to keep her from entering their homes uninvited.Now, in present day, Ruthie lives in Sara's farmhouse with her mother, Alice, and her younger sister, Fawn. Alice has always insisted that they remain on the fringes, living off the land without internet or outside interference. But one morning Ruthie wakes up to find that Alice has disappeared without a trace. When she searches the house for clues, she is startled to find a secret compartment beneath the floorboards that contains two objects. One, a gun. And two, a copy of Sara Harrison Shea's diary.The story the diary tells is one of a mother skating on the edge of sanity, willing to do whatever she can to bring her daughter back even if it means dabbling in dark and dangerous territory. As Ruthie gets sucked deeper into the mystery of Sara's death, she discovers that she's not the only one looking for someone that they've lost. But she may be the only one who can stop history from repeating itself.
