''Warday'' is a novel by Whitley Strieber and James Kunetka. It was first published in 1984 and deals with [[AuthorAvatar slightly fictionalized versions of the authors]] traveling across the United States after a nuclear war to conduct a series of studies and research. Written in the first person, the book is meant to give the impression of what a postwar future would be like.

Notable for its abundance of {{Author Tract}}s and containing numerous [[ScrapbookStory documents from the world it depicts]]. The book was supposed to be the start of [[{{Sequelitis}} a series]], but subsequent projects were abandoned so one of the two authors could write books about his personal encounters with aliens.
!!This book provides examples of :
* AfterTheEnd: In the US (And the Soviet Union) people are trying to survive in the aftermath of a "limited" nuclear war.
* AlternateHistory: Even though the book was set nine years in the future of when it was published time has marched on.
* ApocalypseHow: {{ApocalypseHow/Class0}} Regional/Societal Disruption
* ApocalypseWow: Whitley Streiber's AuthorAvatar relates his first hand experience of the war in New York at the beginning of the story.
* CrapsackWorld: About a third of the US (and possibly more of Soviet) people were killed in the war and the aftermath, if you are not from California you are an illegal alien, one of the main characters is triaged (barred from medical treatment) due to the level of radiation he has received, etc.
** In addition, children with major birth defects from radiation are routinely subject euthanasia.
* DeusAngstMachina: Due to the "limited" aspect of the war, only three US cities are directly nuked: Washington DC, New York, and [[OneOfTheseIsNotLikeTheOthers San Antonio, TX]]. The only real reason why is that James Kunetka is from San Antonio. However, the EMP detonations cause huge damage to infrastructure all over the place.
* DividedStatesOfAmerica / FallenStatesOfAmerica: California has closed its borders, the Southwest has become Aztlan and much of the Eastern US is uninhabitable.
** Other parts of the US are implied to be slowly breaking away - Texas has its own currency (backed by oil), and Washington and Oregon have a joint legislature.
* {{Mockumentary}}
* SelfInsertFic
* UnexpectedSuccessor: The Under Secretary of the Treasury ends up being the self-described caretaker President.
* WorldWarIII: The Soviets start it. Inverted in that actually the Soviets respond to the US starting to deploy Spiderweb, a space based ABM system.
** Someone notes that FromACertainPointOfView, the US actually ''won'' the war - the Soviet Union is stated to be in even worse shape.
