Vowing to make a fresh start, Sarah McAdams has come home to renovate the old Victorian mansion where she grew up. Her daughters, Jade and Gracie, aren't impressed by the rundown property on the shores of Oregon's wild Columbia River. As soon as they pull up the isolated drive, Sarah, too, is beset by uneasy memories--of her cold, distant mother; of the half-sister who vanished without a trace; and of a long-ago night when Sarah was found on the widow's walk, feverish and delirious. Ever since the original mistress of the house plunged to her death almost a century ago, there have been rumors that the place is haunted. As a girl, Sarah sensed a presence there, and soon Gracie claims to see a lady in white running up the stairs. But there's a new, more urgent menace in the small town. One by one, teenage girls are disappearing.
