Roger Hayden’s best-selling series “American Epidemic” and “The Pulse” accumulated over 150 five-star reviews on Amazon. Now he’s back with his most thrilling survival series yet in “Sleeper Cell.” A lone FBI agent. An enemy hell-bent on America’s destruction. The clock is ticking. When a wide network of sleeper cells are activated, America faces a new terror threat unlike anything it’s ever witnessed. Relentless attacks on some of the largest ports in the nation are precursors to an ambitious plan to topple the west and declare a world-wide caliphate. Through years of training, The Islamic State has taken the fight directly to their enemy with untold number of militants living within neighborhoods, cities, and communities, waiting on word to strike. On July 7, 2016, the word came. Explosions. Fire. Poisonous gas. It was only the beginning.
