The Ericksen Connection by Barry Becker

The Ericksen Connection is a spy thriller about betrayal, PTSD, corruption, conspiracy, terrorism, and murder. Mark Ericksen, the former Navy SEAL Team Six operator and executive vice president of EyeD4 Systems, a biometrics defense contractor based in Wilsonville, Oregon, was all about duty, honor, and country. He resigned from his commission in 2002 and, over the next several years, worked for three defense contractors, maintaining his top-secret security clearance while hiding his PTSD.
In 2009, the CIA received actionable intelligence about a Saudi terrorist mastermind aided by Russian arms dealers who needed a classified biometrics encryption communications system from EyeD4 Systems to direct his sleeper cell operatives in launching a horrific nuclear attack on American cities.
