With society falling to shambles, Hank pieces together what few clues he can, on a search that leads him from a college-campus-turned-anarchist-encampment to a crumbling coastal landscape where anti-immigrant militia fend off “impact zone” refugees. *Countdown City* presents another fascinating mystery set on brink of an apocalypseand once again, Hank Palace confronts questions way beyond whodunit. *What do we as human beings owe to one another? And what does it mean to be civilized when civilization is collapsing all around you?*
