World in chaos

Life on earth has been decimated by global thermonuclear war-the Omega Crisis. As surviving government leaders, in underground bunkers around the world, attempt to rebuild a collapsed infrastructure and near-total electrical failure, a new threat appears. A deadly virus has escaped containment at multiple secure storage facilities, threatening the survival of the human race. One of those contaminated is determined to find and kill the president, and he appears to be unstoppable.
While President Gregory McCormick struggles to understand the impacts of the war-on everything from the bunker that's keeping him alive, to the physical world and its environment-he realizes that his long-time friend, Dr. Amos Blund, may hold the secret to restoring power and rebuilding the infrastructure. But Amos is focused on the problems in the Preserve, from personal conflicts, to an overly anxious son, bent on exploring the new world on the other side of the Gemini Gate.
Can Amos keep his priorities straight, and protect his family, and can the president keep his sanity, with the world in chaos?
