Driving back through Wales in a fierce winter storm, forensic anthropologist David Hunter is forced to seek shelter at a remote village in the Eryri mountains. But a one-night stopover becomes something very different after a gruesome discovery in the depths of the local forest. With communications down and the only road washed out by the storm, Hunter is unsure who - if anyone - he can trust. And as long-buried secrets begin to emerge, he knows that, whatever dark past the isolated community might be hiding, there's no one he can call on for help. This time he's on his own.
