An exciting entry in the Pendergast series, benefitting greatly from the prime location in the novel, on an ocean-going super-liner crossing the Atlantic. Throw in a supernatural influence which was more common in the early Pendergast stories and the result is a wild ride. FBI Agent Aloyisius Pendergast and his ward, undergoing a retreat at a remote Tibetan monastery, are asked to retrieve a powerful item that has been stolen by a recent visitor and get it back because its release will trigger the end of the world. The trail leads to the Britannia where things get very complicated, starting with narrowing the search among a couple thousand passengers and crew. Great story. I always enjoy Pendergast stories...the ocean liner setting made me return to reread this after having enjoyed it some years ago shortly after it first came out. Highly recommended.
