内容简介：
"If this strong, fast progressing form of the virus were to be spread somehow to the general population, we could be facing a full-scale outbreak on a level it's hard to imagine. It could turn into a pandemic that would kill thousands, maybe even millions, before we could get it under control-if we can control it" Forces are being developed that could replace nuclear power as the world's scourge. They begin as tiny molecules altered to do the bidding of ruthless terrorists-the marriage of bioscience and nanotechnology to produce a massive pandemic. Four close friends, Dan Cooper, Jud Black, Pat O'Leary, and Jim Barnett, are in the business of exposing malicious hackers who make life difficult for computer users. But what they discover is far more serious. In their quest to learn what has caused a good friend to contract a rare disease-dengue hemorrhagic fever (DHF)-they are thrown into a battle against enemies with staggering powers. Cooper and his pals become the first line of defense against bioterrorists bent on destroying America. The madmen they face have the ability to design and deliver biological attacks that will bring chaos to the world. Can Dan, Jud, Pat, and Jim stop the opening volley in a pandemic with the potential to decimate the United States' population?
