In particular, he has fought to protect humanity by diverting resources to ever larger, more heavily armed starships. But there has been a price - global ecological collapse has ravaged the Earth. Even as Seafort, confronted with the results of his stubborn course, turns his attention to the growing calamity, an orbital assault threatens the future of all mankind.
