The Tabit Genesis — Tony Gonzales

They left Sol in two great ships, carrying with them the last hope for humankind. Destined for different stars, their mission was to ensure the survival of our species. One ship was never heard from again. Decades later, the other arrived at a lifeless world, where the survivors learned that Earth was lost not to famine, but to an alien species determined to eradicate humans from existence.
Man is not alone in the universe, and the last of us are hunted. Driven by strong characters facing tremendous odds, Tony Gonzales delivers SF in the grandest tradition: an epic adventure full of colossal ships, vast battles and unimaginable challenges.
