The girl emerged from the woods. Traumatised and emaciated; close to death, but alive. Her story seemed too terrible to be true. But it was. Every dreadful word of it. When, days later, another desperate survivor is found, a pattern becomes clear. Pairs of victims are being taken; then forced to make an unthinkable decision. And for DCI Helen Grace there is now an unseen killer to be hunted down. Haunted by her own past, Grace has faced down her own demons to rise to the top of her profession. She has coping mechanisms. Now though, there's a new monster to confront. And unless she succeeds, more innocents will die. But worse, some will survive, and have to live with the choice that they made . . .
