After many months of clandestine organisation, Vercingetorix, backed by the druids and leading an army of rebellious tribes, is ready to make his first moves towards independence for his people and the annihilation of Rome's presence in Gaul. Meanwhile, Caesar tends to business in Aquileia, unaware that he is cut off from the bulk of his army in the north by the rebellion. Fronto and his friends are heading for a clash of armies the likes of which the north has never seen, and the Tenth's legate is about to face his most trying year yet facing his opposite number - a chieftain of the Arverni - across the fields and hills of Gaul towards the greatest siege he's ever experienced: Alesia.
It is the eve of destruction. Gaul seethes and bucks more than ever in revolt against the Roman invader, with even Caesar's allies beginning to question their loyalty. A conspiracy of Druids and Kings move the pieces into position in their great game of independence, all led by the powerful exile Vercingetorix. The lands of the Belgae burn in the vengeful aftermath of a winter that saw countless Romans butchered by the Eburone King: Ambiorix. As Rome similarly begins to show its cracks and the triumvirate of powerful men that have held together the crumbling Republic move ever further apart, so Fronto returns to the army, once more seeking his command under the great general. But Caesar has made a vow to end the life of Ambiorix, and naught will stand in the way of that vow's completion - not Gaul, nor Roman, nor reason itself.
4 BC. As tensions build in Gaul and the druids manoeuvre the tribes towards general rebellion, Priscus and the diminishing senior staff of Caesar's army prepare to return to Britannia, this time with a vast army and a will to crush the tribes of that mysterious island. Meanwhile, Fronto contemplates a non-military future as he settles into the life of a married nobleman, socialising with Rome's elite and coming to terms with the decline in his fitness. In this year of rising troubles, Priscus will miss his former commander's presence more than ever. With rebellious Gauls, defiant Britons, vengeful giants, veteran gladiators and dangerous criminals, Fronto is pushed to the limits, driving him to a decision he dreads and a battle for his very life at the steaming, hellish land of Hades' Gate.
55 BC and Caesar's army gathers in the north of Gaul, preparing to drive away invading Germanic peoples and to traverse the dangerous northern ocean bringing punishment to the tribes of Britannia for their assistance of Gaulish rebels. But Fronto's troubles don't stop there. As his burgeoning relationship with Lucilia steps to a new level, so do his responsibilities at home, a situation exacerbated by the disruptive influence of the villainous Clodius in the city, causing trouble and endangering those about whom Fronto cares most. With two troublesome new centurions, a selection of worthless and argumentative senior officers and the suspicious deaths of a number of notables, Fronto's year is about to take a turn for the unexpected.
It is 56 BC. 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. 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. In a year that takes the legions and their commanders to the Atlantic Ocean, the treacherous Pyrenees, and the seething underbelly of Rome, everything is about to change for Marcus Falerius Fronto.
57 BC. The fearsome Belgae have gathered a great army to oppose Rome, and Fronto and the legions assemble once more to take Caesar's war against the most dangerous tribes in the northern world. While the legions battle the Celts in the fiercest war of Caesar's career, the plots and conspiracies against him, both at Rome and among his own army, become ever deeper and more dangerous.
It is 58 BC and the mighty Tenth Legion, camped in Northern Italy, prepare for the arrival of the most notorious general in Roman history: Julius Caesar. Marcus Falerius Fronto, commander of the Tenth is a career soldier and long-time companion of Caesar's. Despite his desire for the simplicity of the military life, he cannot help but be drawn into intrigue and politics as Caesar engineers a motive to invade the lands of Gaul. Fronto is about to discover that politics can be as dangerous as battle, that old enemies can be trusted more than new friends, and that standing close to such a shining figure as Caesar, even the most ethical of men risk being burned.
