In this thrilling final chapter of The Disruption Trilogy, R. E. McDermott once again transports us to a frighteningly realistic post-apocalyptic world of chaos and uncommon courage, and of both hope and despair.

When a massive solar storm takes down the power grid, all order collapses with civilization kept alive only by scattered pockets of survivors who find themselves not only short of critical resources, but facing an unexpected enemy - what's left of their own government.

Survivor resistance stiffens as an increasingly corrupt and tyrannical president clamps down on dissent and seeks to eliminate anyone who might expose his perfidy. With both the defenders of Fort Box in what's left of Wilmington, North Carolina, and the people of the ship Pecos Trader in southeast Texas facing uncertain futures, a resourceful and elusive George Anderson leads government forces on a wild goose chase along the Appalachian Trail, but the future looks grim. Only one man has the credibility and the stature to turn the situation around and fulfill a promise to himself - and the nation.

Simon Tremble, Speaker of the House of Representatives, and the last lawmaker not under control of the corrupt president, climbs out of his hidden hollow and starts south along the Appalachian Trail. He has promises to keep.
