The president's new cybersecurity team, Net Force, is up and running. But a political deadlock in Washington makes the young agency dangerously vulnerable to the criminals, terror groups and hostile governments who would use the digital space to advance their destructive goals. 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.
