In the gripping debut of the Nuclear War four-book series, "Nuclear Winter (TEOTWAWKI - The end of the world as we know it)," the world plunges into its darkest hour as an orbital electromagnetic pulse triggers a catastrophic global nuclear conflict. Amidst the devastation, 90 percent of humanity succumbs to the merciless grip of nuclear winter. Follow the harrowing journey of a select group of survivors as they grapple with the unforgiving new reality. US Army Colonel Thomas Bradley, a brilliant electronic expert from the Defense Intelligence Agency, leads this diverse ensemble. Together, they seek refuge within the unfinished Yucca Mountain Nuclear Waste Repository, their last hope in an unhinged world. Within the cavernous depths of the mountain, these resilient survivors must confront the myriad challenges of a post-apocalyptic existence, all while fending off relentless assaults from a militant faction hell-bent on seizing their sanctuary. Over two tumultuous years, they master the art of subsistence beneath the Earth's surface, their unwavering determination fueled by the dream of a brighter tomorrow. Yet, when they finally dare to venture back into the surface world, they encounter an unforeseen adversary: the radioactive fallout borne by marauding storms, forever altering the once-predictable seasons. Worse still, their battle against the Islamic jihadists, who ignited the global conflagration, proves far from resolved. Forced to retreat to their subterranean refuge, they grapple with the ominous resurgence of nuclear winter, their future shrouded in uncertainty.
