Centauri Dawn

After a forty-year journey from an Earth left teetering on the brink of nuclear Armageddon, the United Nations colonial Starship "Unity" reaches the lone habitable planet orbiting Alph Centauri's primary star, bringing with it the hope of a new beginning for the human race. Hope turns to ashes when, on final approach to the new world, a mysterious malfunction damages the ship, triggering a crisis that results in the death of the captain and a rash of infighting over the ship's undamaged colony pods. The "Unity" breaks apart in space and seven colonial factions are scattered across the surface of the planet.
