In the aftermath of 9/11, remnants of Bin Laden’s Al-Qaeda network quietly infiltrated the U.S. heartland, lying dormant for over two decades. On Thanksgiving Day, they strike—triggering a sinister cyber-terrorist plot poised to plunge America into unparalleled digital darkness. But it’s only the beginning. Paul Knox, a seasoned NSA cybersecurity expert and former Air Force communications officer, is thrust into a clandestine conflict spanning generations. As Knox delves into a complex web of cyber intrigue, he must confront both the mission's high stakes and personal demons, including the unwitting involvement of his daughter, Emma, a brilliant MIT computer scientist who holds the key to the next-generation internet. The narrative intertwines with the origin story of the Liberty Unit's first member, John "Jack" Jouett. In 1791, Jouett embarks on a perilous mission to deliver a critical message from Thomas Jefferson to General Henry Knox, altering the Revolutionary War's trajectory. As the lines between past and present blur, Knox races against time to save his daughter and unravel mysteries that could reshape history. Going dark won’t be a problem for a man who’s spent his life tracking the “worst of the worst” on the dark web. But in this game, every move could be his last.
