The book of the Revelation, the last book of the New Testament, has fascinated readers for two millennia—and confused them. Is it prophecy, or allegory? A man's creation, or the inspired word of God? What does it mean? And how did John write it? He was on Patmos "for the gospel." The church assumes he was in prison there. Was he, or was he there as an evangelist, to spread the gospel?"Preserve The Revelation" is a fictional account of how it might have happened. John is helped by Augustus, who years before helped Luke write his gospel (portrayed fictionally in "Doctor Luke's Assistant"), and by Augustus' two sons. They work with John to write his gospel, epistles, and the Revelation. Many adventures befall these three, in their travels and work, as they fight the courts, the elements, and enemies who want to prevent them from completing their work.
