Harmony
(Book)

The world of Harmony, along with its close-knit colony planets, long ago isolated itself from the rest of the universe. But in a universe where the human-based Confederate Star System fleet finds itself hard-pressed to stand against ever-increasing attacks by the alien Marillon Empire, the Harmonic Empire cannot be left alone. For if the CSS cannot win an alliance with Harmony, the Marils will surely find a way to invade the planet and seize control of the unique and invaluable metal, which only the Harmonites can produce. Yet invasion is far from the only threat the people of Harmony face. The gulf between rich and poor, rulers and ruled continues to widen, threatening to destroy the very structure of their society--while the planet itself is becoming increasingly unstable.
