Prob. best book I've read.
Michael O'Brien presents a thrilling apocalyptic novel about the condition of the Roman Catholic Church at the end of time. It explores the state of the modern world, and the strengths and weaknesses of the contemporary religious scene, by taking his central character, Father Elijah Schafer, a Carmelite priest, on a secret mission for the Vatican which embroils him in a series of crises and subterfuges affecting the ultimate destiny of the Church. The Pope and the Cardinal Secretary of State call him out of obscurity and give him a task of the highest sensitivity: to penetrate into the inner circles of a man whom they believe may be the Antichrist. Their purpose: to call the Man of Sin to repentance, and thus to postpone the great tribulation long enough to preach the Gospel to the whole world.
