Aquila has vanquished the Egyptian Spell-Queen and a Golem in his battles with the divine in Rome and now he taunts the God Jupiter himself in his temple at the heart of Rome. Aquila's allies meanwhile search through the sewers of the Eternal City in search of its wolf-god founders while the Emperor Nero seeks a fifth and final head to complete his ascendance into godhood, and there is only one servant of the gods whose head will fit: Aquila! This is the stunning finale to the first series of the supernatural historical adventure story.
