Warrior of Rome Books in Order

The Warrior of Rome novels drop you into the third century, a time when the Roman Empire is being pulled apart by invasions, civil wars, and religious change. At their centre is Marcus Clodius Ballista, an outsider from the northern peoples who has become one of Rome’s most effective generals.

The early books follow Ballista east to the fortress of Arete, where in Fire in the East he is ordered to hold a small city against the great Sassanid Persian army. Sieges, trench works, religious tension, and fraying morale make the defence as much a struggle inside the walls as beyond them.

From there the story moves through King of Kings and Lion of the Sun into the wider crisis facing the empire. Ballista becomes entangled with court politics, Christian communities, and rival imperial claimants while trying to keep his familia, friends, and men alive on a shifting frontier between Rome and Persia.

Later novels such as The Caspian Gates, The Wolves of the North, and The Amber Road push out across the map. Ballista contends with Gothic sea raids on cities like Ephesus, horse nomads on the northern steppe, and the dangerous politics of his own homeland as civil war breaks out between emperors Gallienus and Postumus.

Across the series you see Roman life from many angles: officers and rankers, senators and merchants, priests, slaves, and travelling entertainers. Sidebottom pays close attention to logistics, languages, and the small details of camps, ships, siege engines, and provincial cities, so the world feels lived in rather than distant.

Several connected novels, including The Last Hour, The Burning Road, and Falling Sky, revisit Ballista at different stages of his career, whether racing across Rome in a single day to stop an assassination or fighting for his family during a slave revolt in Sicily and a brutal campaign in Gaul. You can read them after the core sequence or treat them as gripping stand alone adventures once you know the characters.

What ties the Warrior of Rome books together is a mix of high stakes military action and questions about loyalty, identity, and belonging. Ballista is always slightly at odds with the empire he serves, and watching him navigate friendship, faith, and duty against the backdrop of a strained but still dangerous Rome gives the series its drive.
