Circumference of Darkness

Circumference of Darkness (titled Maximum Impact in the UK) by Jack Henderson is a thrill ride of terrorists, hackers, and political corruption.

After the 9/11 terrorist attacks, Jeannie Reese of DARPA is authorized by the US government to release the ultimate spyware on the Internet - IRIN will catalog all information (net, phone, video) and hunt the people who planned the attack. But when her program begins to track people high up in the government, she is shut out of the process.

With the help of her assistant, her Marine bodyguard, and the publisher of a long-standing underground hacker magazine, she must track down the one man whose computer skills match her own. A man only known by Phr33k.

If Jeannie and Phr33k combine their efforts the US may survive the second wave of attacks planned by an international group of terrorists.
