One Second After
Novel by William R. Forstchen
One Second After is a 2009 post-apocalyptic novel by William R. Forstchen about the aftermath of a devastating electromagnetic pulse (EMP) attack on the United States, following a widowed history professor, John Matherson, as he tries to protect his family and community in a small North Carolina town as society collapses. The book explores the rapid breakdown of modern life, the struggle for survival, and the moral choices that arise when technology fails, becoming a cautionary tale about the vulnerability of modern infrastructure. It is the first book in the John Matherson series and has been discussed in Congress as a realistic portrayal of an EMP threat.

• Genre:
  Post-apocalyptic, science fiction thriller, survival fiction.
