Tara and her brother Kyle are sent to stay with their estranged grandparents when their mother is hospitalised. May and Peter Folcroft seem warm and charming at first, and the house, hidden in the base of the mountains, is idyllic.

But strange things keep happening.

When a storm cuts the phone line, May shifts from doting to obsessive. Tara and Kyle must try to keep up the pretext of a happy family, but an empty journal and locked room provide clues to the unforgivable lies, secrets and decades-old murders entwined with the Folcrofts' history.

And the ghosts are growing restless...
