Gliese 581g

On a six-year journey to Gliese 581g, Zarmina’s World, Daniel Medry and a crew of scientists plan to explore a brand-new world. But when a man-made virus wipes out most of Earth’s population and leaves the rest infertile, their exploration mission becomes humanity’s only hope for survival. Alone in deep space, some worry that a series of equipment malfunctions may not be accidental. As their ship's issues become critical, some fear that someone onboard wants to keep them from making planetfall.

"In the blink of an eye, Earth went from overpopulation to the brink of annihilation. A deadly contagion has slaughtered billions, society has collapsed, and the Earth is in a state of total crisis. Even worse, the raging virus has followed those who thought they had escaped — leaving the fate of humanity itself hanging in the balance. For the ragtag survivors of the Mars colony — the importance of mankind's mission to colonize the Red Planet has never been more obvious. However, there's more than just the dangers of a hostile planet to contend with.
