The figure bent over the small grave and lowered in the black bag. Adult bones would have been heavier. Just a few spadefuls of earth and the secret was hidden…

On a bright spring morning, walkers find a tattered plastic bag containing human remains half-buried in the rolling hills of Somerset. The bones belong to Rosie Dawson, a little girl who disappeared ten years ago. Detective Anna Gwynne is back at work after a case that nearly cost her her life. The trail is stone cold, but Anna will stop at nothing to find the killer, and escape thoughts of her own dark past.

Then another little girl is abducted near a river bank on the hottest day of the year, and her sister can’t remember anything about the man who took her. Nobody thinks the cases are connected, but then Anna finds a photo of her that matches an old one of Rosie. In the same dark room. The same concrete walls. The same stony floor.

The killer is bragging.

With just two photos and a witness too young to help, can Anna find the killer in time to save a little girl’s life?
