One Second After is a 2009 science fiction novel by American writer William R. Forstchen. The novel deals with an unexpected electromagnetic pulse attack on the United States as it affects the people living in and around the small American town of Black Mountain, North Carolina.

Released in March 2009, One Second After and was ranked as number 11 on the New York Times Best Seller list in fiction in May 2009.^[1] A trade paperback edition was released in November 2009.^[2]

John Matherson is a professor of history at the local Montreat Christian College. A retired U.S. Army colonel and Gulf War veteran, he had moved to Black Mountain with his family when his late wife Mary, a native of the town, was dying from cancer. He is now the widowed father of two daughters, Elizabeth and Jennifer.

At 4:50 p.m. (16:50) Eastern Daylight Time on the second Tuesday of May, the first day described in the book's narration, the phone lines in the town suddenly go dead, along with all the electrical appliances. Within hours it becomes clear that this is no ordinary blackout. Every modern electrical device is disabled, destroyed by what Matherson is beginning to suspect was an electromagnetic pulse (EMP) attack on the United States.

The United States has effectively been returned to the 18th century, with few 21st-century people able to deal with such conditions. Matherson later remarks that survivors have had to rely on the technology of the early 16th century. His immediate concern is his twelve-year-old daughter, Jennifer, who has Type 1 diabetes. Without a constant supply of insulin, which requires refrigeration, she will die.

The book explores how the whole community responds, as many others face similar crises. Matherson's experience and character help him with the town's residents. Hundreds of motorists are stranded when their vehicles stop. They get into town, making the residents feel threatened by the numbers of people needing help. An immediate concern is food. No refrigerators or freezers are running, nor are grocery stores receiving supplies.

Residents of the nursing home in town, where Matherson's elderly cancer-stricken father-in-law is being cared for, are at risk. The elderly and frail need refrigerated medicines, and many require constant nursing care. The EMP has disabled the nursing home's generator. There are no AM/FM radio broadcasts, no television, no Internet, and thus, no communication with anyone outside the town is possible. It takes two months before a working antique telephone can connect Black Mountain with the nearby town of Swannanoa.

Matherson's in-laws are car collectors who happen to own a 1959 Edsel, and a Mustang. These are not affected by the EMP as they have no sensitive electronics. Similarly a resident's vintage airplane is newly useful, because it has no vulnerable electronics.

Without modern sanitation and supplies, diseases surge. Minor wounds become seriously infected, and the community has soon exhausted its supply of antibiotics. The social order in Black Mountain begins to break down. It is too late in the year to plant and harvest crops. Suddenly, skills not needed in several generations have become critically necessary. The town organizes its young and able-bodied to defend against a marauding band of cannibals. When they attack, there is a violent and deadly battle with high fatalities.

Matherson leads several battalions of college students into battle against the marauding Posse. The college's resource officer is killed and two-thirds of the students die. After the battle the Posse leader is captured and hanged on the interstate. Matherson releases several remaining Posse members, saying that they were not going to do any more harm.

After a while, the extreme shortages of food require rationing. Increasingly, Matherson assumes a growing leadership role as the situation deteriorates. He and other leaders struggle with the multiple issues and moral choices. Matherson's daughter, Jennifer, eventually dies due to a lack of insulin and is buried near the family home.

One year later, the U.S. military arrives to rebuild and aid the town. It is learned that the EMP was generated by three nuclear missiles launched from offshore container ships. One was launched from the Gulf of Mexico and detonated in the upper atmosphere over Utah, Kansas, and Ohio. The container ship was sunk by an explosion immediately after the missile launch; no one knows who was responsible for the attacks. Another missile was fired from off the Icelandic coast and detonated over East Europe and Russia. This launch affected major cities such as St. Petersburg and Moscow and everything in between. Another nuclear missile was detonated over Japan and South Korea.

The U.S. government believed that an alliance between Iran and North Korea conducted the attacks, and retaliated by striking both countries with nuclear weapons. The U.S. withdrew all of its overseas military forces to aid in rebuilding and humanitarian work at home. The EMP attack brought down Air Force One, and the U.S. president died upon impact.

One year after the EMP attack, the United States is described as having 30 million survivors, down ninety percent from a pre-attack population of 300 million. The People's Republic of China is occupying the U.S. west coast with a 500,000-strong occupation force, and Mexico occupies its former territory of Texas and the American Southwest, as a protectorate against China.

The book also explores the increasingly intimate relationship Matherson develops with Makala Turner, a single, childless nurse among those stranded by the pulse.
