Now, Haley Walthers is on the run. Her friend and mentor, Ben Anderson, is missing, and the one man she hoped never to see again is the only man who can help her.

Together, they set out to find Ben - and learn the secret that a soulless corporate syndicate will do anything to possess. With a merciless enemy closing in, Haley and Sam must prevail in a brutal race through a vast wilderness. Against all odds, they'll risk everything to secure the extraordinary finding that, in the wrong hands, could wreak untold devastation, starting with the Pacific Northwest - and ending with the world...
