Terrorists are holding America under siege. Their method is as ingenious as it is deadly: using commercial aircraft purchased from a failing domestic airline, they deploy bombs out of a modified rear-entry stair on unsuspecting and critical targets. The first attack is on Los Angeles International Airport. Thousands are killed, closing down air traffic and creating a national panic. As the country watches helplessly in horror, a second airliner flies over Dallas/Fort Worth and drops a bomb on the main control tower. The President orders Lieutenant General Robert Blocker to re-establish security in the skies before the White House is next. Blocker's response to the crisis is drastic, as it needs to be...until the terrorists strike Denver, the Memphis. A deadly game of cat-and-mouse escalates to a breathtaking climax in this eerily prescient thriller.
