Surrender Serenity (Salin's Salvation, Book 1)

Eon’s people always took care of their planet of Salin, having learned from their ancestors mistakes. When a virus ravages the female population leaving most females dead and those who survived infertile, their people search endlessly for a way to save their people from disappearing from existence, but nothing seems to work. Out of hope and desperate, a seer gives them one last hope, EARTH.
