An Ebola-type virus unleashed at Disney World. Random car bombings on interstate highways. Children's medicine bottles laced with poison. All the work of a demented but brilliant terrorist determined to blackmail the White House and bring the U.S. government to its knees.

FBI agent Mike Devlin breaks rules--and cases. But the hard-edged Devlin has never faced a manhunt as enormous and challenging as this before. Racing against the clock, scrambling for leads, clashing with fellow G-men, Devlin must break the case before one lone madman holds hostage the security of an entire nation.
