A house full of secrets...

The McBride house lies on a remote Scottish island, isolated and abandoned. A century ago, a young widow and her son died mysteriously there. Last year a local boy, visiting for a dare, disappeared without a trace.

A woman alone at night...

For Zoe Adams, the house offers an escape from her failing marriage.

But when night falls, her peaceful retreat is disrupted-scratches at the door, strange voices-and Zoe is convinced she is being watched.

A threat that lurks in the shadows...

The locals tell Zoe the incidents are merely echoes of the house's dark past. Zoe is sure the danger is all too real-but can she uncover the truth before she is silenced?
