Summary
When the National Security Agency intercepts and decodes an obscure email message indicating a severe threat to the US, the American President considers his options. What if the same technology that made the interception possible could be used as an… offensive weapon? Armed with satellites, ships, planes, and an array of sophisticated hardware, the NSA proves as competent at covert action as it is at spying. Success leads to a permanent NSA Group that acts directly for the NSA Director. Followed by "Deep black: biowar". 2004.
