This novel is closely based on Bible prophesies about the Resurrection or "Rapture" of the Church and the seven year Tribulation which follows. In that sense this is not a work of fiction. However, fictional characters and situations are intertwined with the actual order of prophesied Biblical events to make those events come alive and be more understandable to the Reader. The primary purpose is to inform about what the Bible says, but it is also meant to be interesting and entertaining, because the Bible is not boring.
When the Rapture of the Church happens it will be generally seen as an unexplained "Vanishment" by unbelievers of that time as they attempt to explain it away. With all believers removed from the earth, the remaining restraints on evil will be greatly diminished, and the world will be ready to accept extreme evil in ways not otherwise possible. But many who are left behind will be awakened by the Rapture and will believe in Jesus Christ as their Savior. These new believers will see it for what it really is, a wake-up call. Jews will especially be awakened to the reality that they missed their prophesied Messiah. A period of Tribulation will then engulf the world for 7 years and the forces of evil personified by the Antichrist will severely persecute the new believers. Many will be killed -- martyred in great numbers because of their faith. The thin veil of civilization will be ripped apart from top to bottom as the basest instincts of sinful mankind are unleashed. This seven year period of Tribulation will be the most evil of all human history, and as a result God will allow judgments and disasters of types and magnitudes never before seen on the earth.
The Tribulation will be a time of evil lawless dictators who destroy individual freedoms and trample the rights of anyone they do not agree with, especially the new believers. The forces of evil will have their seven year revelry, but God will avenge the persecution of His believers. Evil will have its last stand, but Truth and Justice will triumph as the Lord returns at the end of the Tribulation to destroy the forces of evil and institute His 1000 year Millennial reign under perfect environment on this same earth, which only He can put in place.
But first, the Vanishment awakens a world in slumber.....and triggers the seven year countdown to Armageddon.
