Vanguard Lindsay Rooney has faced the undead hordes of Inferi Scourge and lived to tell the tale, but she has also suffered horrible losses. Like millions of other civilians, she had hoped that The Bastion would recover after a team of modified soldiers eradicated the undead hordes of Inferi Scourge that infested their valley. Yet the city still crumbles around them, along with any chance of survival.Lindsey's growing friendship with Torran MacDonald, an officer with the Science Warfare division, is her only solace as the decline of the city continues. When food riots fill the streets, martial law is enacted, and the upper echelons of government battle for control of the city, Lindsey is conscripted by her superiors to embark on a dangerous mission into the dead world beyond The Bastion. To add even more complications, Torran and the SWD join the squad. Soon, Lindsey realizes that her mission is more than what it seems, and there are secrets that could both destroy The Bastion and take her life.
