The apocalypse strikes without warning. A mysterious geomagnetic event that sweeps the globe, leaving a powerful amnesia in its wake. In the blink of an eye, the human race is robbed of the most basic skills learned in childhood: reading, writing and the ability to speak. Civilization crumbles, plunging the world into an age of unparalleled barbarism. From the ashes emerge a handful of survivors, largely unaffected by the change. Alone, they must brave a dangerous and chaotic world in order to reach the only known refuge: a camp set in the foothills of Salt Lake City, Utah. There lies food, shelter and maybe even answers. But standing between them and safety is more than bands of armed thugs and bloodthirsty cannibals. A new evil is gathering. One that's eager to destroy the last vestiges of life on earth and finish what it started, once and for all. The survivors: A man who awakens in the bowels of a secret laboratory with no memory of how he got there and only an enigmatic tattoo to guide him. A Coast Guard sailor searching for a killer who may not be what he seems. A mother of two and recent widow, struggling to protect her family from a world gone mad. A former CEO and full-time scumbag determined to do whatever it takes to thrive in this new apocalyptic wasteland.
