Earth is dead. No one has seen the surface in five years. Earth died at the hands of pollution, corruption, and nuclear war; humanity has survived in bunkers far below Earth's radioactive surface. Now, with the bunker systems failing, humanity needs to find a way to survive. Five of the world's greatest minds left are being sent on a dangerous mission: find a way to survive on the surface or watch the human race die. Josephine was a biomedical Engineer before the world ended, but will her past impede her mission? Atlas fought his way onto the research team, and no one knows why he is there. Orion journeyed to the surface for the girl he loves, but will she ever forgive him? Jade and Sebastian want the same thing, to live without having to wear safety suits and masks and bask in the sun again. Confronted with a destroyed homeland, and haunted by secrets from their pasts, the five must fight and use their minds to survive. They always hoped to be remembered, but will they be able to save mankind?
