'The story I now commence is rich in vicissitudes, grim with warfare, torn by civil strife, a tale of horror even during times of peace.’ Tacitus, The Histories AD 68. The Emperor Nero’s erratic and bloody reign is in its death throes when Gaius Valerius Verrens is dispatched to Rome on a mission that will bring it to a close. With Nero dead, the city holds its breath and awaits the arrival his successor, Servius Sulpicius Galba, governor of Hispania. The Empire prays for peace, but it prays in vain.

The Roman grip on Britain is weakening. Emperor Nero has turned his face away from this far-flung outpost. The Druids are on the rise, spreading seeds of rebellion among the British tribes. Roman cruelty and exploitation has angered their British subjects. The warrior queen Boudicca will lead the tribes to war. Standing against the rising tide of Boudicca's rebellion is Roman Tribune, Gaius Valerius Verrens, Commander of the veteran legions at Colonia.

Emperor Nero’s grip on power is weakening. In every shadow he sees an enemy and like a cornered animal he lashes out at every perceived threat. His paranoia settles on the figure of Gnaeus Domitius Corbulo, Rome’s greatest General who leads the imperial legions in the East. So popular is Corbulo with his men that he effective presides over an Empire within an Empire. Is Corbulo preparing to march against Rome and take the purple?

Rome, AD 68. Nero has committed suicide. One hundred years of imperial rule by the descendants of Julius Caesar has ended, and chaos rules. His successor, Galba, dismisses the incorruptible Germans of the Imperial Bodyguard for the crime of loyalty to the dead emperor. Ordering them back to their homeland, he releases a Batavi officer from a Roman prison to be their prefect. But Julius Civilis is not the loyal servant of empire that he seems.

The Romans invaded Britannia in AD 43 confident of victory. They swept through a divided and ill-equipped enemy, scattered across tough terrain. But one man was not prepared to surrender. Caratacus - quick-witted youngest son of a a tribal king - had been trained from birth to be a warrior of power and grit. Sent to be schooled by the Druids in his boyhood, his training meant that an already strong and cunning prince returned to his father's kingdom as a war machine.
