"In this action-packed thriller in the New York Times bestselling Tom Clancy's Op-Center series, America's elite task force must take down a group of ruthless domestic terrorists determined to paralyze the country through extreme acts of violence. They are known as the Black Order. Self-proclaimed patriots and survivalists, they refuse to surrender their values and beliefs to the left-leaning cultural and progressive forces threatening their nation. Military veterans and high-tech specialists, they've begun a savage war from public assassinations of politicians and celebrities to high-profile bombings, striking without warning or mercy. The Black Order wants nothing less than complete capitulation from the US government, giving them free rein to make their ideologies the law of the land. Only Op-Center's Black Wasp, a skilled team of military operatives answerable to the President, can defeat these militant revolutionaries. But even as Admiral Chase Williams and his agents force them on the run, the Black Order possesses a weapon of mass destruction that they will not hesitate to unleash against millions of innocent civilians."-- Provided by publisher.
