Detective Inspector Hulda Hermannsdottir is sent to the isolated island of Ellidaey to investigate and soon finds haunting similarities with a previous case – a young woman found murdered ten years ago in the equally desolate Westfjords.

As Hulda navigates a sinister game constructed of smoke and mirrors she is convinced that no one is telling the truth, including those closest to her.

But who will crack first? And what secrets is the island hiding?
