After the events that led to Kannon's arrest, Colin continues his mission to find out about the Weaponeer's next steps - and that perhaps even he underestimated the organization. A threat emerges with plans to destabilize the world order, putting Ninjak in a race against time to prevent a disaster - but of course, that alone would not be enough. Involved in a web of manipulation, power and the ghosts of his own training, Colin realizes that the real challenge will once again be happening within himself - at the same time that he decides how far he is willing to go for what he believes in.
