Climate change moved faster than anyone anticipated, and the Earth, along with many of its inhabitants, is dying. When a military convoy arrives to pick up Devin Rossi and Karissa Decker, along with dozens of other bewildered people, the two have no idea they are part of a group selected by the government to be transported to a space station preparing for the colonization of another planet. They are members of the Chosen. On their way to the military base, their convoy is attacked and Devin and Karissa learn the real reason behind their selection. Their attraction grows as they struggle to survive and wrestle with the decision to continue on to the base as part of the Chosen, which means leaving millions of others behind to die. Will they face an uncertain future together, or will the cost be too high?
