In this medical thriller Dr. Henry Parsons, an unlikely but appealing hero, races to find the origins and cure of a mysterious new killer virus as it brings the world to its knees.
At an internment camp in Indonesia, forty-seven people are pronounced dead with acute hemorrhagic fever. When Henry Parsons--microbiologist, epidemiologist--travels there on behalf of the World Health Organization to investigate, what he finds will soon have staggering repercussions across the globe: an infected man is on his way to join the millions of worshippers in the annual Hajj to Mecca. Now, Henry joins forces with a Saudi prince and doctor in an attempt to quarantine the entire host of pilgrims in the holy city... A Russian émigré, a woman who has risen to deputy director of U.S. Homeland Security, scrambles to mount a response to what may be an act of biowarfare... already-fraying global relations begin to snap, one by one, in the face of a pandemic... Henry's wife Jill and their children face diminishing odds of survival in Atlanta... and the disease slashes across the United States, dismantling institutions--scientific, religious, governmental--and decimating the population.
