Jennifer McMahon, author of the #1 New York Times bestseller Promise Not to Tell, returns with a thrilling new novel about hidden secrets, unsettling choices, and the sometimes unimaginable bond between mothers and daughters. Set in West Hall, Vermont, the town is known for its proliferation of mysterious disappearances and the revival of ancient legends. Perhaps the most mysterious case is that of Sarah Harrison Shea, who in 1908 was found dead in the field behind her home, just months after the tragic death of her daughter Gertie. Now, 19-year-old Ruthie lives on Sarah's farm with her mother, Alice, and her younger sister, Fawn. Alice insisted on living outside the busy city, a decision that suddenly proved precarious when Ruthie woke up one morning to find Alice had vanished without a trace. Searching for clues, she is stunned to find a copy of Sarah Harrison Shea's diary hidden beneath the floorboards of her mother's bedroom. As Ruthie delves into the mysterious details of Sarah's fate, she discovers that she is not the only person desperately searching for a missing person. However, she may be the only one who can prevent history from repeating itself.
