Alex Hunter, code named Arcadian, wakes up with no knowledge of who he is, in the care of a woman he doesn't recognise, in a country not his own. But there is a calling deep within him, to return home to Black Mountain.
Formed a billion years ago, the Appalachian's Black Mountain hosts a terrible legend. Recently some hikers have gone missing, and the rescue team sent to search for them has not returned.
A survivor is then found half-alive, covered in blood - blood revealed to be not quite human.
Alex must confront an age-old enemy of man and discover the truth about his past, and confront the horror that stalks the frozen mountain, and also the one haunting his very soul.
