Dr. Jack Stapleton and Dr. Laurie Montgomery must race against the clock to prevent an unthinkable catastrophe in this "frightening" (Publishers Weekly) novel from the #1 New York Times bestselling author hailed as "the master of the medical thriller" (The New York Times).

Experts do not question whether a bio-terrorism event will occur in the United States, only when. . . .

New York City cab driver Yuri Davydov is an angry, disillusioned Russian émigré poised to lash out at the adoptive nation he believes has denied him the American Dream. A former technician for the vast Soviet biological weapons system, Yuri possesses the technical knowledge to carry out his vengeance on a horrific scale, especially after teaming up with a pair of far-right survivalists who share his abhorrence of the United States government.

Dr. Jack Stapleton and Dr. Laurie Montgomery are confronted with two seemingly disparate cases in their work as forensic pathologists in the city's medical examiner's office. They hardly suspect that the deaths could be related, but soon they begin to connect the dots, and the question then becomes whether or not they will solve the puzzle before Yuri and his comrades unleash the ultimate terror: a modern bioweapon.
