The Great Tribulation is the third and last novel of the Perilous Times series.
The novel goes through the last three and a half years of the seven year Tribulation Period. The world leader gets "assassinated" and teams up with Lucifer to rise again and become the Anti-Christ. They begin persecuting Israel and the one hundred and forty-four thousand witnesses for Christ as the Bowls of Wrath are poured out and more of God's judgments are unleashed on the unredeemed of Earth. Everything leads up to the final battle between Lucifer's forces and God at Armageddon.
