The fate of mankind may soon take a surprising turn when a new disease that turns its victims green before they die appears in a pristine mountain community. Suspecting biological terrorism, Major "Di" Johnson and her team quarantine that community and the nearby resort towns. The imminent arrival of summer tourists would spread the disease worldwide and doom the human species, one way or another. Major Johnson recruits David Tollner, a lustful but lost vacationing scientist. Their romance blossoms as they race to discover how to stem the strangest and most dangerous disease in history before it either dooms or transforms the human species. This is an astonishingly plausible story, based on current biomedical science and technology and the recent creation of synthetic cells.
