Series background & context
Marcus Valerius Aquila sits at the heart of the Empire series. When readers first meet him in Wounds of Honour, he is a Praetorian centurion from a powerful senatorial family, suddenly condemned to death after Emperor Commodus turns on his father. Taking the alias Marcus Tribulus Corvus, he flees to bleak northern Britannia and hides in an auxiliary cohort on Hadrian's Wall.
The early novels follow Marcus as he learns to lead from the front in a hard used frontier unit. Campaigns against the northern tribes, especially the brutal chieftain Calgus, drag him into ambushes, night marches and desperate set piece battles in rain soaked hills and bogs. Life in the Tungrian cohort is noisy, foul mouthed and tight knit, and much of the tension comes from Marcus trying to keep his true identity secret from both his comrades and the emperor's hunters.
As the series progresses, the scope widens. After stabilising the British frontier, Marcus and the Tungrians are sent to Germania and then Dacia, dealing with masked bandits, plague shaken towns and the defence of gold mines that help fund the empire. Riches shows how a small, professional cohort can be shifted from one crisis to another, and how friendships and rivalries survive the constant churn of marching, skirmishing and rebuilding shattered units.
Eventually Marcus is drawn back to Rome itself. In books like The Emperor's Knives he steps into the capital's back alleys, gladiator schools and senatorial villas, hunting the cabal responsible for his family's murder. These stories weave personal revenge into wider plots involving Praetorian politics, street gangs and imperial paranoia, while still returning regularly to the familiar rhythm of drill, campaign orders and muddy encampments.
Later volumes push Marcus and his patron Scaurus far beyond the old northern frontier. The cohort fights Parthian cataphracts on the empire's eastern border, stalks a dangerous priestess and her followers through the forests east of the Rhine, and is dispatched to Egypt and the Red Sea trade routes to face threats from the kingdom of Kush. The geography changes from misty moorland to deserts and great cities, but the through line remains the same, a tight band of soldiers trying to hold their formation while history crashes around them.
In the most recent books the action moves into the era of civil war that follows Commodus. Marcus and Scaurus find themselves serving Septimius Severus during the Year of the Five Emperors, marching across Thrace and Asia Minor against rival claimants to the throne. Battles between Roman legions replace clashes with tribal warbands, and the cost of endless campaigning weighs heavily on even the most hardened veterans.
Across the whole Empire sequence, readers can expect gritty, ground level military adventure built around loyalty, revenge and the day to day work of keeping a unit alive. It is a series for anyone who enjoys the smell of campfires, the clatter of armour and the sense that history is decided as much in muddy ditches as in marble palaces.
