The Fate of the World Rests on Their Shoulders. . . In the future, medical science has perfected the process of rebuilding a mortally-wound person using organs and limbs created using their own DNA. The military version of the process results in "Reclaimed" troops that are bigger, faster and stronger than regular, or non-reclaimed, troops. The 419th Combined Assault Unit of the United States Marine Corps consists of both regular and reclaimed personnel, male and female. The 419th CAU is commanded by reclaimed Major John Coles and his second-in-command, reclaimed Captain Jeri Blake. The commander of the 3rd Element of the 117th Armored Cavalry Regiment attached to the 419th is Captain Samantha "Sam" Carpenter, a regular troop. The 419th will soon be tested to their limits with the most important mission of their lives...the preservation of the human race. A Chinese research team created a genetically-engineered warrior which was faster and stronger than reclaimed personnel in the hopes of removing the human element in battle. However, its savagery and aggressiveness made it impossible to control. After a disastrous battle on a tiny Pacific island called Lanzhou, which resulted in the loss of nearly 3,000 U.S. and Chinese troops and the ultimate destruction of the creatures; it was mandated by the U.N. that no genetic bio-weapon research was ever to be allowed again. Jeri's reclamation was a result of her involvement in that horrific engagement. Three years later, the Vietnamese decide to ignore this mandate and recreate the beasts to sell them as breeders to whomever could afford to pay their price. Because the U.S. and Chinese had battled these creatures before, they are again tasked with destroying this unspeakable menace to humankind. As second-in-command of the 419th, Jeri must once again face the monsters which caused her reclamation. Her previous nightmarish encounter with them has her facing her own personal demons of near-paralyzing fear and doubts
