Jack Widow, the ultimate loner, becomes the bait to save a kidnapped girl only to find himself at the center of a terrorist conspiracy where his enemies are both foreign and domestic in the million-selling action-thriller series. Widow is in Miami when he's mistakenly arrested, which puts his name into the system. A mysterious phone call from the US Secret Service, and Widow is on a plane to DC to face a covert emergency. The emergency: someone kidnapped the Secret Service Director's only daughter. The kidnapper's demands: 1: Tell no one. 2: Assassinate the President.
