It is 56bc. As Fronto and his friends winter in Rome and Caesar in Illyricum, trouble is brewing in the north. The tribes of Armorica, driven to desperate action by the harsh rule of Crassus, raise their standards in defiance of the Roman eagle, causing a chain reaction that threatens everything the legions of Caesar have achieved. Can the general's commanders stamp out the fires of rebellion before the whole of Gaul is ablaze? Meanwhile, in Rome, the conspiracies against Caesar take an unexpected turn, plunging Fronto and his friends into a world of crime, violence and intrigue that threaten everything the legate cares about. The city is in turmoil and the republic is teetering on the brink of disaster. In a year that takes the legions and their commanders to the heaving Atlantic Ocean, the treacherous valleys of the Pyrenees, and the seething underbelly of the greatest city in the world, everything is about to change for Marcus Falerius Fronto.
