When the world ends, where do you go? Fifteen-year-old Peter Russell has waited all his life to escape a dying Earth and head for the stars. Days before his ship is scheduled to leave, the corporation in charge of the evacuation disappears, abandoning the rest of humanity. The Exodus is over, with thousands left behind. No messages. No excuses. No way out. Left behind on a dying planet with no power and no food, Peter must find a refuge for himself, his mom, and his little brother. Taking a chance on a rumor, the family begins the terrifying journey to the Dome, a self-sustaining colony located hundreds of miles away. Along the way, they must protect themselves from the desperate remains of humanity. Even if they survive the journey, the Dome harbors secrets deep inside. What do you do when there's nowhere to go?
