46 BC. Pompey is dead, Egypt is settled and Rome is controlled by the loyal Marcus Antonius. As the new year looms, Rome's greatest general and dictator Julius Caesar moves precipitously to take on the last stronghold of the rebel faction: Africa. Crossing against all advice in the middle of winter, with minimal forces and little forward planning, the campaign almost dies before it begins, legions scattered across the sea by vicious storms, the general putting ashore with just a single legion and his most trusted veteran commander: Marcus Falerius Fronto.  

Winter, 48 BC. Caesar and his small force are trapped in the Egyptian city of Alexandria. Caught up in the dynastic struggles of the House of Ptolemy, the consul has sided with the clever and ruthless Queen Cleopatra. Her brother and fellow monarch, Ptolemy XIII, languishes in the palace, a hostage of Caesar's, while a huge army under the command of the Egyptian General Achillas closes on the city to free him. 

It is 48 BC, and Caesar is master of Rome, but Pompey is at large in the huge recruiting grounds of the east with a core of powerful officers, nominally representing the senate in absentia. As the general deals with matters in the city, his army gathers at the coast, waiting to cross the sea and fight that worst of all conflicts: civil war.

25 BC. Titus Cervianus is no ordinary soldier. A former surgeon from the city of Ancyra, he's now a capsarius—a combat medic. Cervianus is a pragmatist, a scientist and truly unpopular with his legion. The Twenty Second Deiotariana have been sent to deal with uprisings and chaos in Egypt. Yet the Twenty Second is no ordinary legion either. Founded as the private royal army of one of Rome's most devoted allies, the king of Galatia, their ways are not the same as the other legions, a factor that sets them apart and causes friction with their fellow soldiers. 

The war in Gaul is over, but the fight for Rome is only just beginning. Denied his consulship by the senate and nearing the end of his term as governor, Caesar waits at Ravenna with one legion, making a last attempt at reconciliation. Threatened with prosecution if he returns to Rome, just one path is becoming clear: war against the senate. Fronto and Galronus are bound to the service of the Proconsul, facing a war against other Romans, and able neither to prevent nor avoid it. 

51 BC. In the aftermath of the dreadful siege of Alesia, the tribes of Gaul lie broken and sparse, and yet the fires of rebellion still burn in the hearts of a few. As Caesar and his army continue to pacify the land wherever revolt can be found, a new conspiracy is rising. Lucterius of the Cadurci, survivor of Alesia, seeks to raise a new great revolt, building an army in his homeland, while a small group of dangerous warriors embark upon a secret and dangerous mission to rebuild all that was lost in that great siege.

In the depths of the desert on the empire's Eastern Frontier, the Roman army lays siege to the city of Nicopolis. Estranged from his beloved Enica to keep her safe, centurion Flavius Ferox has secured his freedom after being framed once again. His next quest: to uncover traitors within the Roman ranks. As the siege builds, widespread corruption seethes and soldiers are murdered in cold blood. Meanwhile, Ferox's investigation brings him closer and closer to the imperial court, and uncovers connections to Hadrian himself...

Betrayal by friend and foe alike beset Sir John Hawkwood as he enters the murky world of Italian politics. He will emerge from the experience as a true leader of men but first he has to outwit his enemies of which there are many. With Montferrat secured from the Savoyards and with the White Company now firmly in his hands, Sir John Hawkwood leads his men to Pisa where they have been hired to fight the Florentines. The hero of Poitiers is about to enter a world of treachery, intrigue and double dealing for which he is quite unprepared.

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.

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 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.  

The fate of Rome, and thousands of lives, rests on the shoulders of one man. After murdering his brother, and taking the position of Emperor for himself, Caracalla orders a brutal purge of the supporters of Geta. Meanwhile, Caracalla’s ally Marcellus is captured by Syrian warriors. They wish to use his son, Avitus, as a puppet emperor to affirm a new Eastern Empire. Caracalla orders Silus to track down and rescue Avitus, rumoured to be Caracalla’s child.

Rufinus is dead, crumpled at the base of a cliff in far-off Dacia. Or so the world believes. Back in the west, secretly in the entourage of the fierce Septimius Severus, the young hero moves in the shadows with fellow conspirators in an attempt to finally bring down the would-be tyrant of Rome: Cleander. Under assumed names and in a variety of roles, the former Praetorian conspires with some of the most important men in Rome, bringing the city to the very brink of disaster in a grand and complex plot to cause the fall of the untouchable chamberlain. 

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.

Winter, 1362. After decades of successful campaigning in France, Thomas Blackstone, once a common archer, has risen to become Edward III's Master of War. But the title is as much a curse as a blessing. Success has brought few rewards: his family—bar his son Henry—is dead, slaughtered; his enemies only multiply. Death, in so many guises, beckons. As he battles to enforce his King's claim to French territory, Blackstone will assault an impregnable fortress, he'll become embroiled in a feud between French aristocrats, he'll be forced into pitched battle in the dead of winter.
