Winter People by Jennifer McMahon
Ooh! Here is a good horror story for those of you who like ghosts, murder and haunting. Meet Ruthie(16) and younger sister Fawn. Their mother, Alice, disappears one night and in their search for her they find hidden a gun, two wallets of people they don't know and an old diary from Sara a woman who live in their farmhouse in 1908. The farmhouse they live in is next to a rock formation called Devil's Hand. Local legends say it is a dangerous and haunted place, a place where people go missing ever since Sara went crazy after the accidental loss of her only child Gertie. Or was it an accident?
