His company is flourishing, and his relationship with former government agent Daryl Haugen has intensified since she became a part of his team.
But the West is under its greatest threat yet. A revolutionary, invisible trojan that alters data without leaving a trace—-more sophisticated than any virus seen before—-has been identified, roiling international politics. Jeff and Daryl are summoned to root it out and discover its source.
