Publisher's Synopsis
After a traitor brings down his whole division, O'Brien is left with few options but to run. However, finding some loose information from a deceased comrade, he uncovers a run-down, overlooked squad of men in need of a leader. Things could not be better...except they're not. The world is reportedly losing its breathable air fast, but for the help of an age-old legion of men, the world will dry up, and man will go extinct. So the oxygen sphere is built, and not too long after, rumors begin to spread. Was there ever an oxygen shortage? Who is really behind this monstrosity? And where does all the money for it go? For a world that never thought it would make it through World War III-but did!-it now looks bleak as on the horizon things are building for the biggest test mankind has ever faced: Oxygen War. The price of existence has just gone up.
