In Central Europe, an unknown enemy mounts a crippling high-tech assault against the organization's military threat-response unit on its home base. The strike casts suspicion on a core member of Net Force, threatening to destroy the cyber defense group from within. But as they race to track down their attackers, the stakes are suddenly ratcheted higher. For a global syndicate of black hat hackers and a newly belligerent Russia are hatching a mysterious, shadowy scheme for world domination from a place known only as the Secret City.
Their attack protocol: leave Net Force in ashes while Moscow and its Dark Web allies set the stage for a devastating strike against the United States.
Unless the men and women of Net Force can regroup in time to stop them.
