This is a story - perhaps the story - of the clash between two great civilizations of the sixth century of the Common Era, when the Roman Empire had crumbled into dust; the struggle for Rome, and for Italy, between the Eastern Roman Empire of Byzantium, ruled by Justinian, and the Gothic warrior tribes who had captured Italy under their legendary king Theodoric.

We see this epoch through the eyes of different personalities at the centre of these events, which shook the world as they knew it; most are historical figures and some are imaginary but typical; Justinian and his beautiful and scheming wife, Theodora; the great commander Belisarius, immortalised by Robert Graves; Totila and Teias, two Gothic kings, one as bold and bright as the sun and the other as black as night; and Cethegus, the Prefect of Rome and the last of the Romans, whose cold and calculating nature runs through the book like a steel thread, who will stop at nothing to regain the ancient city, and who, in the end, fails and redeems his many crimes with a hero's death.
