A civilization-ending comet is headed for Earth. Two days before impact, thousands of mysterious pods land in a swath across North America. When people touch them, the pods open. Anyone who climbs inside is carried away. No one knows where the pods came from and no one knows where they go, but finding one is David Williams’ only chance to save his family from the end of the world … and escaping Earth is just the beginning. 

THE PRESERVATION OF SPECIES trilogy begins with RULE OF EXTINCTION, a post-apocalyptic science-fiction adventure filled with unforgettable heroes, terrifying monsters, and heart-pounding action.
