Synopsis: From the back cover of the Pocket Book first edition: "The fight against the root of all evil requires a master! Despite being a time traveler and literal Renaissance man, Dr. John Dee has adjusted admirably to life on Earth in 2100. But his mercantile genius is once again put to the test when he and his twenty-second-century comrades, Morgan d'Winter and Kelly Edwards, are called upon to protect their world from the machinations of an alien renegade posing as a messiah. When the chips are down, only John Dee can save the past, present, and future from this pretender and his expanding army of human zombies!"
