Deep in a secret, underground laboratory, a group of scientists find themselves in danger. Achieving cutting-edge breakthroughs in genetic engineering, they have created powerful viruses, the likes of which the world has never seen. They're playing god. But their creations have the power to turn on them--and do. The scientists work for the U.S. military, developing biological weapons of mass destruction in direct violation of federal and international law. But it's a necessary evil, for while these brilliant men and women create microscopic monsters, they work even harder to try to develop antidotes to stop them. Some monsters can't be contained, though. Or stopped. When an accident unleashes one of their creations, Craig Leland and his team watch in horror as the virus attacks and kills one of their own. But their nightmare is just beginning, for all is not as it seems. In a race against time, with no way out, Craig must fight for his team's survival--and the woman he secretly loves.
