In this page-turning thriller, reformed cybercrook turned cybersniffer Mac Brody is hidden inside the Federal Witness Protection Program and paid by major corporations to 'twist doorknobs' - that is, to see which computer netwerks are safely locked and which are dangerously unsecured.

When an attractive CEO of a large investment bank challenges Mac to break into its cutting-edge security system, he finds a way to move $100 million from one account to his own, then back again. As it turns out, though, the money is owned by a secret fundraising group for a terrorist network, and they don't find the tampering amusing.

As he dodges assassination attempts, Mac finds himself unraveling a digital money trail that takes him into a world in which Muslim terrorists are still operating with impunity in the United States, protected by religious freedom acts that allow them to spread hatred and raise funds, sometimes with government help. Mac will eventually find his way into the heart of the United Nations . . . and uncover an assassination plot that reaches into the inner circle of the White House.
