The escape is over. The fight has just begun. Against all odds, Bryce and the other Escapers have returned home from the alien prison camp, but the Imjac still controls the world. Eager for revenge against the alien invaders, Bryce is recruited by the Alien Combat Force, the last remnants of America's armed forces. The ACF wants Bryce for his ability to use alien technology. Bryce just wants to join the fight against the Imjac. The other soldiers resent Bryce, and the leaders of the ACF refuse to let him fight. Worse, the Imjac have continued their harvesting, enslaving young humans for their mining camps. Can Bryce prove himself to the ACF and find a way back to the island prison to defeat the Imjac?
