This is a tale of vengeance.Six months after the death of his mentor, Cole Traske is returning to work as the new leader of his former interplanetary shadow-ops squad, Penumbra. As they head towards their first target, Cole must balance the responsibility of leadership, the squabbling of his pilot and demolitions man, and the inexperience of their young new sniper.With a heavily scarred body and a history shrouded in secrecy, Cole has tried his best to steer clear of the curious, believing that his past should remain right where it is--in the past. Unfortunately for Cole, his hopes for an uneventful return to work are shattered by a chance encounter with a spectre from his past, Tobias Navarr. Tobias's return, and its tragic consequences, propel Cole headlong into the pursuit of revenge that will take him beyond the edge of the galaxy and perhaps the edge of reason itself.It's time to stop running. Retribution awaits.
