Air Force One crashes into the sea, with the US President aboard. Is it an accident? Yellowstone National Park erupts in the most devastating volcanic catastrophe ever known. But, when evidence points to foreign terrorists, vengeance is swift and merciless.

Darkness falls across the globe, society collapses, liberty vanishes, and soon forces wielding unfettered power are transforming the United States into the greatest threat to global survival.
