The Year of the Quiet Sun is a 1970 science fiction novel by American writer Wilson Tucker, dealing with the use of forward time travel to ascertain future political and social events.

Initially assuming her to be a reporter interested in a controversial book he just published on the Dead Sea Scrolls, she informs him that she works for the federal Bureau of Standards and that she is recruiting him for a physical survey of the future via a secretly constructed "TDV" or time displacement vehicle.

Instead he focuses his attention on the project, which is soon ordered by the President of the United States to embark on their first mission, a trip two years into the future to discover whether he wins the 1980 presidential election.

They also learn that the nation is under martial law after a failed attempt by the Joint Chiefs of Staff to take over the government by coup d'état, one thwarted because of the advance knowledge the time travelers will bring back of it.

Not having chosen a date, and disillusioned by his experiences on the 1980 trip, he arrives at an indeterminate point in "2000-plus", by which time the power from the base's nuclear reactor has been disrupted, causing the chronometers set up for the travelers to shut down.

In her introduction to the 1979 Gregg Press edition of the novel, writer Sandra Miesel praised the novel as "an intimate drama of Armageddon played out within the boundaries of Will County, Illinois by a cast of five principals."

She noted the way Wilson linked the America of the novel and the Qumran community of ancient Palestine, which are introduced through Chaney's background as a biblical scholar who had published a book on the Dead Sea scrolls prior to the start of the novel.
