Lt. General Nick Angriff loses everything he loves in the present day and so he becomes the leader of a military unit that is cryogenically frozen for the time when America will need him and his troops the most. He wakes fifty years into the future to find the USA destroyed and predators roaming the ruins. Stalked by assassins, Angriff has to prepare for war while avoiding murder. Because the only wall still shielding survivors from slavery and death are the men and women of The Last Brigade.
