The Remnant by Tim Lahaye
Nicolae Carpathia has his enemies’ right where he wants them: massed at Petra, a million strong. The Trib Force’s aliases and even their safe houses have been compromised, forcing Rayford, Buck, and all the members to flee for their lives while trying to maintain their overt opposition to the Antichrist. All pretense is gone, even on the part of the Antichrist, as the planet hurtles toward the ultimate showdown between good and evil.
As the battered earth reels under judgments from heaven, Global community leader Nicolae Carpathia tightens the screws on anyone who refuses to proclaim total allegiance to him. He has a million of his enemies just where he wants them: massed at Petra and within striking distance of devastating firepower. Meanwhile, the Tribulation Force is compromised, forcing Rayford Steele, Buck Williams, and the others to run for their lives.
