Plague

A state of emergency is declared across America as a new strain of bacillus
sweeps across the nation with alarming speed and devastation - a combination of
bubonic and various other plagues caused by incorrect disposal of the nation's
waste products. There is no known antidote.
When the President informs the
nation that it's their duty to protect disease free zones, that's exactly what
they do. The book then turns into a war between those who are infected,
those who aren't, and those who think everyone else is ... the
result is nothing short of a blood-bath.
