Black Widow

An enemy with power far beyond anything they could comprehend.

The US government''s most lethal weapon is back. Code-name Devlin, he operates in the darkest recesses of what is right and wrong, and survives without praise or thanks. So when international cyber-terrorists release a deadly and cunning band of radical insurgents to breach the highest levels of national security, it is Devlin who must take down an enemy bent on destroying America - an enemy more violent and ruthless than the world has ever known.
