'Parthian Dawn' is the second volume of the adventures of Pacorus the Parthian and his companions - the fierce and proud Gallia, the ex-Roman centurion Domitus, the scout Byrd and the sorceress Dobbai - as they battle for their lives against the backdrop of the clash between the ancient world's two greatest empires. After three years fighting by the side of Spartacus, Pacorus and his followers have escaped from Italy in the aftermath of the defeat of the slave rebellion. Made a king by the ruler of the Parthian Empire on his return, he has married his beloved Gallia and made the city of Dura Europos on the banks of the Euphrates his home. But his new kingdom is seething with discontent and surrounded by hostile desert nomads who are the sworn enemies of the Parthians. The aged King of Kings, the man who has united the Parthians for decades, then dies to cast a shadow of uncertainty over the empire, which erupts into full-scale civil war as one of the empire's most powerful men, Narses, attempts to seize the high crown by force. Pacorus is forced to fight both Narses and his scheming ally, Prince Mithridates, to preserve the realm and his own crown. And then the Romans, taking advantage of Parthia's internal troubles, launch their own invasion of the empire. Will Pacorus and indeed the Parthian Empire survive the conflict that engulfs them on all sides?

When Rome transgresses upon his father's domain that lays between the Tigris and Euphrates rivers, Pacorus, a prince of the Parthian Empire, is sent to exact revenge. After a string of victories Pacorus and his men are captured in Cappadocia, clapped in chains and sent to Italy to live out the rest of their days as slaves. But fate intervenes and Pacorus and his companions are saved from a living hell by a renegade gladiator named Spartacus. In gratitude, Pacorus agrees to help Spartacus build his army as Rome musters its legions to crush the slave uprising. And so begins an epic adventure of glory and savagery played out across the length and breadth of Italy, as Spartacus defeats the armies of Rome and Pacorus leads his horsemen to victory after victory. But will Pacorous and the slave army escape from Italy, and will he win the love of the fierce and proud Gallia before the most powerful man in Rome, Marcus Licinius Crassus, takes the field against Spartacus?
