Sanctuary — Matthew Mather

A new world arises from the ashes of the old… But the fight for survival has only begun. In the Day of the Nomad, oceans flooded the continents, the earth split open and poured darkness into the skies. Jessica Rollins survived, but at what cost? The key to humanity's survival may lie in the backpack she recovered from her father, in the mysterious data he collected more than thirty years before. His final words to her circle around and around in her head--just who is Ufuk Erdogmus? And what is...sanctuary?
