A deadly plague strikes America's cities. Hospital ERs are jammed, chaos reigns in the streets, men and woman are dropping like flies. Someone has taken the war on drugs into their own hands and poisoned the narcotics supply. And most chilling of all: the majority of Americans approve! Summoned back to Washington by the director who exiled him, maverick FBI agent Mark Beamon is given the thankless task of discovering who's behind the full-page ads that have suddenly appeared in newspapers across the country, giving addicts a simple choice: . Quit or die. Teamed with a female field agent as icily analytical as he is intuitive, Beamon begins a desperate "all-points" search, racing against the drug cartels, the Cosa Nostra, and the random violence on the streets, as the poisoned drugs take their grim toll.
