Retired Army Delta Force operator Luke Ellis, 17-year-old teen Annie Dedham and her 12-year-old brother Darren, along with young Loudoun County deputy sheriff Alec Holman, are in a race against time to prevent the destruction of humanity. To succeed, they need the help of a mysterious woman scientist. Only she can stop Armageddon from taking place. There's a huge problem, though: Terrorists are rampaging through the small Loudoun County hamlet of Lucketts and they're after the same scientist. What Ellis and his little band do over the next several hours will decide the fate of humankind.
