Arden and her friends thought that they’d found their salvation from a dying Earth in the underground utopia of Future Lab but their hopes for making a life in the city are dashed when the former Director comes back into power and wants to free the hominees, a race of artificially intelligent beings, from their dependence upon humans by making humanity extinct. Arden and Killian’s relationship status may be up in the air but Arden knows that she can count on Killian to come up with a plan to save them all. That is until a catastrophic event strikes and separates them, possibly for good. Arden must learn that in the end, the only person she can count on for her salvation is herself.
