On the graveyard shift at the Deep Space Surveillance observatory in Hawaii, an air force airman steps out for a smoke, looks up, and catches sight of a shooting star?no, two shooting stars, strangely paired, and too bright against the night sky. This can't be right, he thinks ? The airman is right. The objects are not stars but asteroids on a collision course with earth, and there is almost no time to prepare an unsuspecting world for the all but total devastation soon to come. But a retired army colonel and his family in western Pennsylvania, a group of cadets at the Virginia Military Institute, the president of the United States, and a handful of others across the country manage to survive the asteroid impacts and the towering twin tsunamis that follow?only to discover that the worst is far from over. For in the wake of the devastation, small, life-bearing objects are falling to earth ? and a plan laid out 400 years in the past begins to unfold.Without Warning takes the reader from the frozen depths of a world hurled into nuclear winter to a final battle for the very survival of the species?a journey the reader will not soon forget.
