内容简介：
A mysterious epidemic breaks out in the American Midwest, killing hundreds of thousands of people. In an ultimatum to the U.S. Government, a Mexican terrorist group claims responsibility for developing and releasing a new type of biological weapon of mass destruction (WMD) by means of genetic engineering. With panic and chaos engulfing the nation and the threat of a second attack looming, a massive manhunt is launched to track down the terrorists. Written by a real scientist with authentic detail, this novel provides a chilling warning of the technical feasibility of building a powerful new type of biological weapon that has thus far been overlooked, but that is more easily constructed and delivered and yet more potent than any previously conceived weapon. But don't be terrified: For the time being at least, it's still fiction.
