The year is 2099. The United States, Russia, and India have successfully established permanent colonies on the surface of Mars. When the colonies inexplicably lose all contact with Earth, they are forced to enter a fight for survival that no one could have anticipated. An inter-colonial committee has been called together with leaders from each of the three colonies to address the crisis they now face: thirty thousand people, stranded, alone, on a harsh and unforgiving planet. The lack of support from Earth threatens the colonists’ supplies of food, water, and fuel, while the alien landscape of Mars can create entirely new problems for the committee to face. The actions of this small group of colonists could wipe out what may be the last vestiges of humanity, but they may also lead the way to the extraordinary achievement of sustainable life on a new world.
