From publisher blurb:
While leading a group of diverse people is never easy, leading a group of people assembled through a sheer need for survival in a world controlled by the Living Dead is extremely dangerous.
Over the past several months, the characters have faced hordes of Living Dead, watched allies die, and discovered a bestial species with greater-than-human strength and endurance. Along the way, they have managed to avoid starvation, betrayal, and traps meant to maim or kill them. None of that, however, has prepared them for what they now face.
A revelation that will rip the prison down from the inside out.
