MAYFLOWER

In the twenty-second century long-distance space travel has been mastered. Humans have colonized many planets. The last Christians have left earth and settled on a planet they call Mayflower. They purchased the planet from one of the corporate states that owns the Earth and its colonies. They were told that the planet was uninhabited. It was not.
Travel to the planet takes many years and return travel is not practical. Mayflower, the planet, circles a dim star but it does not rotate. One side, where the settlers have established their towns has a permanent gloomy daylight. The other side of the planet is dark and cold yet not devoid of life as warmth seeps through the planet.
The first generation of humans born on Mayflower has grown up. They are facing many challenges to survive and establish a world free of the old-Earth.
