West Hall, Vermont, has always been a town of strange disappearances and old legends. The most mysterious is that of Sara Harrison Shea, who, in 1908, was found dead just months after the tragic death of her daughter. Now, in present day, nineteen-year-old Ruthie lives in Sara's farmhouse with her mother, Alice, and her younger sister. Ruthie wakes up one morning to find that Alice has vanished without a trace. Searching for clues, she is startled to find a copy of Sara Harrison Shea's diary hidden beneath the floorboards of her mother's bedroom. As Ruthie gets sucked deeper into the mystery of Sara's fate, she discovers that she's not the only person who's desperately looking for someone that they've lost.
