In the distant future, the Human Primacy has conquered much of the galaxy. Led by the Council of Callers, humanity has united in worship of the Calling Tower, a mysterious crystalline structure embodying the living consciousness of Earth itself. In the shadows, one among the Callers has been working for centuries to bring about his own transformation into a being of pure power, unfettered by the limits of flesh. In his quest for godhood, this mad Caller will risk the lives of billions and the future of humanity! Only a small group of unlikely companions stands in the way of catastrophe on a galactic scale. A stunning combination of expansive science fiction and luxurious fantasy, Calling Tower is high adventure at its best. "A promising start to a serious-minded space-opera epic." - Kirkus Reviews
