G581: Omnibus #1

This omnibus edition contains the first three books of the Gliese 581g series.

Book 1: Their mission was to build a second home for humanity - but who knows if humanity will survive long enough to reach it? Setting forth on a six-year journey to Gliese 581g - Zarmina's World - Daniel Medry and a crew of fellow scientists planned to explore a brand-new world potentially ripe for colonisation - 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.
 

Book 2: 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. 

Book 3: Earth lies devastated and empty. Over 99.6% of the population have succumbed to the deadly ESH virus. More have perished in the civil wars and anarchy that followed. With humanity on the brink of extinction, most made infertile by the virus, newly-elected President Madeline Chen is forced to make unthinkable choices—robbing millions of their basic human rights to ensure mankind's survival.
