Twilight of Empire Book VI


Head of Zeus, January 2019

"Thrilling, dramatic… Castus, a man past his prime, resolutely pagan, vulnerable and brave, shines in this superb conclusion to a landmark series.”

Sunday Express

"Ross is wonderful at conjuring up this Rome - an empire that is sprawling and unwieldy, beset by religious schisms and threatened on its frontiers. Fans of Harry Sidebottom or Ben Kane who are yet to discover Ross will devour this series.”

The Times

"The excellent Twilight of Empire series marches on… Hot, sweaty, gripping and bloody - ‘Triumph in Dust’ is bloody good too!”

Sunday Sport

When the simmering conflict between Rome and Persia threatens once again to ignite into open war, there is only one man the Emperor Constantine can trust to defend the eastern frontier.

Aurelius Castus has fought long and hard for Rome. When the summons comes to command an army once more, he obeys with a heavy heart. Is he still the fearsome fighting machine of old?  Will his young, ambitious officers respect and follow a great soldier of former days? 

But when tragedy strikes the imperial household, Castus must race to defend the last bulwark standing against the might of Persia. In the pitiless heat of the Syrian desert, engulfed by whirling sandstorms and facing a fearless, treacherous foe, Castus knows that the fight ahead will be the fiercest he will ever know, and very probably his last.

Twilight of Empire Book V


Head of Zeus, January 2018

"Utterly thrilling... packed with historical and military details... My favourite element of Imperial Vengeance, though, is its depiction of the imperial family. All of these figures are absolutely fascinating, while the dynamic between them is both enthralling and lethal. Ian Ross has secured Constantine a firm place in Roman military historical fiction.

Victory will have its Price

Aurelius Castus is one of the leading military commanders of an empire riven by civil war, but age is telling upon him. As the emperor Constantine grows ever more ruthless in his pursuit of total power, and more forceful in his promotion of Christianity, Castus fears that the world he knows and loves is slipping away.

On the eve of the war’s final campaign, Castus discovers that the emperor’s son Crispus, hero of the west, aims to depose his father and restore the old ways of Rome. As the armies march and the fleets sail, Castus knows that greater dangers lie beyond the battlefield, and victory will have its price.

With a sadistic torturer on his trail, and all that he loves under threat, Castus must choose between honour and survival, and face a final confrontation with the most powerful man in the Roman world, the ruler he has sworn loyally to serve: the emperor Constantine himself.





Twilight of Empire Book IV


Head of Zeus, January 2017

It’s the early 4th century and the Roman Empire is divided. Crispus, Emperor Constantine’s heir, is sent northwards to bring order to the Germanic tribes.

But Aurelius Castus, commander of Crispus’s army, discovers the most dangerous enemies are the most secret. This tense, immersive novel is driven by the forceful yet always human Castus who is driven to the limits of endurance to protect what he holds dear. The best of a fine series, this also stands very well on its own.

When a treacherous act of murder throws the western provinces into turmoil, Aurelius Castus is ordered to take command of the military forces on the Rhine. But he soon discovers that the frontier is a place where the boundaries between civilisation and barbarism, freedom and slavery, honour and treason have little meaning.

At the very heart of the conflict are two vulnerable boys. One is Emperor Constantine’s young heir, Crispus. The other is Castus’s own beloved son, Sabinus. Only Castus stands between them and men who would kill them.

With all that he loves in danger, Castus and a handful of loyal men must fight to defend the Roman Empire. But in the heat of battle, can he distinguish friend from enemy?




Twilight of Empire Book III


Head of Zeus, January 2016


The Roman Empire is on the brink of civil war. Only Maxentius, tyrant of Rome, stands between the emperor Constantine and supreme power in the west.

Aurelius Castus, promoted from the ranks for valour and loyalty, is now a tribune in Constantine's army. But great honour brings new challenges: Castus is tormented by suspicions that his aristocratic wife, the mother of his child, has been unfaithful. And as Constantine becomes increasingly devoted to Christianity, Castus is forced to ask himself whether he is backing the wrong man. 

All know that the coming war will decide the fate of empire. But Castus's own battle will carry him much further - into the shadowy realms of treachery at the heart of Rome itself.

Rome is in peril. The old order is changing - and Aurelius Castus has been summoned back from Britain to find himself caught up in a treasonous conspiracy threatening to bring down the Emperor Constantine.

Rewarded for saving the emperor's life in battle, Castus is promoted to the Corps of Protectores, the elite imperial bodyguard. The swords around the throne.

But he soon discovers the court to be as dangerous as the battlefield; behind the gilded facade of empire, there are spiralling plots, betrayals and seductions. A nest of traitors. And one relentless enemy.
