As the politicians bring the nation to the brink of war, a mysterious book appears offering directives and carrying wisdom to prepare people for Adjustment Day.

People pass the word only to those they trust most: Adjustment Day is coming. They've been reading a mysterious book and memorizing its directives. They are ready for the reckoning. Adjustment Day, the author's first novel in four years, is an ingeniously comic work in which Chuck Palahniuk does what he does best: skewer the absurdities in our society. Smug, geriatric politicians bring the nation to the brink of a third world war in an effort to control the burgeoning population of young males; working-class men dream of burying the elites; and professors propound theories that offer students only the bleakest future. When Adjustment Day arrives, it fearlessly makes real the logical conclusion of every separatist fantasy, alternative fact, and conspiracy theory lurking in the American psyche.
