The secret history of another Rome

The mid-2600s, Ranulf becomes Supreme Pontiff of the Empire of Rome at Alexandria, a patriarchy run by priest-bureaucrats called Librarians. After twenty-two years on the throne, Ranulf's memories flood back to him, from the time he moved to Alexandria with his mother to his present situation resulting from his choices, his training and his relationships. Ranulf's life has been a quest for truth, not the half-truths of the Librarians and their Secret History, but an understanding of how action rather than static dogma is the path to the future. Guided by mysterious strangers from another time and his own innate curiosity, Ranulf searches for this understanding. Why do the Librarians hide facts from their ruler? What will Ranulf do as he gradually uncovers the truth? How will he respond when he finally understands?
