Major damage in Memphis is almost unthinkable, and FEMA better have their A game on because the looting will ensue in hours, and riots very quickly thereafter. Which really means that it's gonna get bad, because I have no confidence whatsoever in the government.
It's one year after two New Madrid earthquakes have devastated the Mississippi Valley. Battalions of foreign peackeepers are occupying Tennessee, at the invitation of the President. Phil Carson, (from "Enemies Foreign And Domestic"), and three strangers are hiding in a well-stocked cave, which is a guerrilla fighter's lair. Across the region Kazakh "contract peacekeepers" are wiping out the last remaining American holdouts, who have rejected the federal government's order to abandon their homes and move to "relocation centers." This scene is in the middle of the novel.
