Caden Dechert, chief of a U.S. mining station on the moon, just cares about doing his job and keeping his crew alive in Luna's unforgiving environment; the commander of a rival Chinese base feels the same way. Governments back on Earth, however, are edging toward war, and Dechert watches as minor poaching and sabotage escalate into murder. Many begin to question whether humans can learn to control themselves well enough to survive in space. As more people die violently, Dechert tries to find the murderer and talk sense to the people in power.
