Book two starts five months after the end of the first one; with Alexander struggling to return to his squadron, and Angela fighting to survive on the front lines without his amazing skills or powerful presence. With the affects of the Eden program plaguing his every living moment, a broken and battered Alexander finds that in order to return to his friends and fight against the alien abominations that have stolen nearly everything from him, he must first survive the most intense and gruelling training the American Military has to offer. He must make it through Marine Corps Boot Camp, a training program designed to destroy young men and women, and then build them back up into one of the most elite fighting forces in the world. His second in command, Angela, however, finds herself stuck out on the front lines with the other members of the squadron as she is now forced to somehow take his place as the Squadron Commander of a tired, and depressed outfit that is down two members. Yet, with the U.N.E. threat pushing against NATO forces and threatening to invade Germany, she and her friends must fight on and give Alexander time to return.

The year is 2043 and the nations of the world find themselves almost powerless against an unknown enemy known as Unknown Entities, or U.N.E.'s. The Worlds best weapon against these hideous creatures from space are the giant Mech's and their pilots who stand on the front lines and fight a never ending stream of U.N.E.'s to protect their lands, nations, and friends from harm. Two young pilots from very different worlds come together at a secret weapons facility as the next generation of Mech's are ready to hit the front line. One is a young British pilot born and raised in combat who is haunted by horrible memories, while the other is an American pilot who has never seen combat but has never found anything or anyone that can best her. Can these two young officers set aside their differences and pride and do what needs to be done? Or will they falter when it matters most?

25 years after an infection spread that has made people into flesh eating monsters, Alex is forced to escort Max across a post-apocalyptic United States in faith that they have found something man kind has been waiting for. While in their journey they run into other people that are also desperate to do anything to survive.
