A small, northeastern town is crippled after a mysterious electromagnetic pulse causes a massive blackout, leaving residents stunned and unprepared. But the loss of power is only the beginning.

Communications and mobility have been disabled with vehicles stopped dead in their tracks for miles. Grocery stores, banks, hospitals, and other services no longer function. Cell phones, computers, televisions, and radios are rendered inoperable. In the chaos that follows, one family embarks on a journey of survival in a vastly different world, changed within a flash.

Rob Parker owns a prepper shop in downtown Nyack, where he resides with his wife, Mila, and their two children. Following the strike, on the morning of September 12, 2016, he takes immediate action to hunker down in their bug-out cabin in the mountains along the Hudson River. Most of the town is clueless with little or no understanding of what has happened. But Rob knows that things will only get worse with emptied shelves, raided ATMs, no running water or sewage—a complete breakdown of law in order.
