200 years ago humankind boarded a spaceship and left behind a dying planet. Now they plan on returning on the anniversary but things aren't the same as they were. In the spaceship, all that anyone knows of Earth is what they read in old textbooks. The new generations of humans who have never seen their original home planet finally set foot on the ground. They thought they were the only people on Earth but they're not alone. Eden was only a teenager when the asteroids hit. She's been awake and surviving on her own for five years and frozen in time for much longer than that. When she sees a familiar face in the new crowd of people, she must search for answers about what happened to her and the new community she must now learn. Peter has only ever known space. His prayers for something new are answered when he is finally able to step onto Earth and breath fresh air but things aren't as he expected as Peter has to question who and what are the real dangers. Amidst these new people and new inventions, Eden and Peter have to not only figure out how to get along with the each other but also save the people from a new contagious illness.
