Patricia Mullner is trapped in a nightmare no parent should ever experience. Three years ago, 17-year-old son Andrew vanished without trace. There was no note, no goodbye and no body has ever been found, and now her days are spent in a fog of heartache and alcohol, crying to husband Thomas about their lost boy. But Patricia is more than just a grieving mother, and as Andrew's disappearance starts to unravel the perfect family she's built with Thomas, it seems that the actions of her past may be back to haunt her. Because someone is watching from the shadows - someone who knows exactly what Patricia is hiding. Someone who will stop at nothing to take revenge - and might just hold the key to Andrew's disappearance.
