Last Man Standing has the essential elements of a terrific David Baldacci novel: a tough but tender-hearted hero, dirty dealings in the nation's bureaucracy, and a roller-coaster plot. Web London, a member of the FBI's Hostage Rescue Team, froze up on a drug raid and thus became the sole survivor of a remote-controlled ambush that killed six of his compatriots. Now the only witness has disappeared and the inside man on the botched raid has gone underground.
