A war is coming, the outcome of which will decide the fate of the entire planet. The Sirujians have gathered, ready to execute the final act of their devastating invasion, one that threatens to eliminate the struggling remnants of the human race once and for all. Yet for the first time in history, all mankind stands united, and though weakened, willing to fight to the end.

Caught up in this struggle and separated by half the globe, Clay Morton and Charity Collins are forced to fight horrific battles of their own in a desperate struggle to see each other again before it's too late. From the Marsh tribe infested lands of Tanzania to the mysterious stronghold of 6623R, danger looms in every form, with the deadly consequences of secrecy and betrayal threatening to defeat humanity before the Sirujians even get the chance.

The stage is set for a battle of Armageddon level, yet the odds are terribly tilted. For reasons unknown, the Sirujian leader's dangerous abilities grow stronger with every day that passes, and his army waits with cruel anticipation. To stand a chance, Clay Morton, Captain Dawn, and the brilliant Dr. Gatling must consider the unthinkable - choices whose consequences are almost as terrible as defeat itself.
