In a chilling new look at the world of bioterrorism, the best-selling author of The Hot Zone explores the return of smallpox, eradicated in 1979 but now returning in a deadlier, genetically engineered form, and the crusade of three doctors to not only uncover the mastermind of the 2001 anthrax attacks but also prepare for future bioterrorist actions.
