Apollyon - Tim LaHaye & Jerry B. Jenkins (First edition; Left behind series #5)

Apollyon is book five in the continuing drama of those left behind at the Rapture. It's the most shocking and explicit portrayal yet.

The world holds its breath as the Tribulation Force ventures to Jerusalem for the great Meeting of the Witnesses. Tens of thousands of the 144 000 witnesses prophesied in Scripture meet at Teddy Kollek Stadium to sit under the teaching of their pastor-teacher, Tsion Ben-Judah.

Rayford Steele and Buck Williams, charter members of the Force, have gone from employees of Nicolae Carpathia to international fugitives. Rayford, finally discovering the shocking truth about Amanda, must flee before the grand conference begins. The two witnesses at the Wailing Wall proclaim warnings to the "one who sits on the throne of the earth," and Carpathia himself makes a surprising appearance at the stadium. 

The Tribulation calendar moves ever closer to the halfway point, which the two witnesses call "the due time." Meanwhile, the fourth Trumpet Judgment strikes the solar system, crippling life on earth.

The next three judgments are to be so much worse than anything that has ever come before that an angel flies about heaven, warning the earth of the three woes. The fifth Trumpet Judgment - a plague of scorpionlike locusts led by Apollyon , a chief demon of the abyss - is so horrifying that men try to kill themselves but are not allow to die.
