Alaska changed everything. Project Threshold lost key people and is still trying to sort itself out. Berger moves up in the ranks and begins training a new leader. He crosses paths with a dangerous psychic but gets sidetracked tracking down Katie and Jessie before they disappear forever. The team goes head to head against something decapitating people in the desert, killers in the skies, and they try to stay out of the path of a vengeful ghost that will not stop . . .
