The Siege

by Nick Brown

Published 21 July 2011

270 AD
Rome has ruled Syria for over three centuries. But now the weakened empire faces a desperate threat: Queen Zenobia of Palmyra has turned her Roman-trained army against her former masters and the once invincible legions have been crushed. Arabia, Palestine and Egypt have fallen and now Antioch, Syria's capital, stands exposed.
Cassius Corbulo is a young intelligence agent fresh from officer training. He has been assigned the menial task of rounding up wounded legionaries but then urgent new orders arrive. He is the only ranking Roman officer left in the line of the Palmyran advance. He must take command of the fort of Alauran, the last stronghold still in Roman hands, and hold it against the enemy until reinforcements arrive.

What Cassius finds at Alauran would daunt the most seasoned veteran, let alone a nineteen year old with no experience of war. A mere scattering of divided and demoralised legionaries remain, backed up by some fractious Syrian auxiliaries and a drunken Praetorian Guardsman. With the Palmyrans just days away, Cassius must somehow find the discipline, resourcefulness and courage to organise the garrison, save Alauran and secure Rome's eastern frontier...

The Imperial Banner

Published 7 June 2012

272 AD

The Roman Emperor Aurelian has defeated Queen Zenobia and crushed the Palmyran revolt.

Faridun's Banner, hallowed battle standard of the Persian Empire, has fallen into Roman hands and is to be returned to the Persians as part of a historic peace treaty. But on the eve of the signing the banner goes missing.

Recalled to Syria, imperial agent Cassius Corbulo is charged with recovering the flag. Accompanied by his faithful servant Simo and ex-gladiator bodyguard Indavara, Cassius must journey across the dangerous wastes of Syria to the equally perilous streets of Antioch. He and his companions face ruthless brigands, mysterious cults, merciless assassins and intrigue at every turn.

The Far Shore

by Nick Brown

Published 18 July 2013

When the deputy commander of Rome's Imperial Security Service is assassinated on the island of Rhodes, Cassius Corbulo swiftly finds himself embroiled in the investigation. Assisted once more by ex-gladiator bodyguard Indavara and servant Simo, his search for the truth is complicated by the involvement of the dead man's headstrong daughter, Annia.

Braving hostile seas, Cassius and his allies follow the assassin's trail south aboard a ship captained by a roguish Carthaginian smuggler and manned by his disparate, dangerous crew. Their journey leads them to the farthest reaches of the empire; to a ruined city where the rules of Roman civilization have long been abandoned, and a deadly battle of wits with a brutal, relentless foe.

The Black Stone

by Nick Brown

Published 5 June 2014

AD 273.

Obsessed by the solar religions of the east, the emperor Aurelian sets out to obtain every sacred object within his realm. But one - a mysterious rock said to channel the power of the sun god - lies beyond his reach. Warrior-priest Ilaha has captured the legendary stone and is using it to raise an army against Rome.

For Imperial agent Cassius Corbulo and ex-gladiator bodyguard Indavara, stopping him constitutes their greatest challenge yet. Assisted by a squad of undercover soldiers and a Saracen chieftain, they trek south across the deserts of Arabia, encountering sandstorms, murderous money-lenders and a ruthless German mercenary.

And when they finally reach Ilaha's mountain fortress, they face thousands of warriors who will give their lives to protect him ... and the black stone.
