Oneiros

For thirty years, asteroids have pummeled Earth and civilization is on the edge of annihilation. Major Asher Gray is about to retire when the military asks him to undertake one final, and secret, mission: They want him to travel to the Oort cloud station, at the edge of the solar system, to find the source of the rocks before the planet is destroyed. Asher quickly realizes that he isn't the only one trying to solve this mystery and the forces he is up against won't hesitate to kill him to accomplish their goals. He must race against time to keep his family together, save Earth, and unravel the secret behind the deadly attacks on the planet

Oneiros ultimately examines how far one must be willing to go to get back everything they have lost and asks its readers:

Would you be willing to give up your family to save Earth?
