AD, 98. The bustling army base at Vindolanda lies on the northern frontier of Britannia and the entire Roman world. In just over 20 years' time, the Emperor Hadrian will build his famous wall. But for now, defences are weak as tribes rebel against Rome. It falls to Flavius Ferox, Briton and Roman centurion, to keep the peace. But it will take more than just a soldier's courage to survive life in Roman Britain.
Flavius Ferox is the hard-bitten centurion charged with keeping the peace on Britannia's frontier with the barbarian tribes of the north. Now he's been summoned to Londinium by the governor, but before he sets out an imperial freedman is found murdered in a latrine at Vindolanda fort. Ferox must find the killer. As he follows the trail, the murder leads him to plots against the empire and Rome itself. Bandits, soldiers and gladiators alike are trying to kill him, old friends turn traitor, and Ferox is lured reluctantly to the sinister haunts of the old druids on the isle of Mona.
Flavius Ferox, Briton turned Roman centurion, is charged with keeping Rome's empire intact. But from his base at Vindolanda on the northern frontier of Britannia, he feels enemies closing in on him from all sides. Ambitious leaders await the chance to carve out empires of their own while men nearer at hand speak in whispers of war and the destruction of Rome. And now new threats are reaching Ferox's ears. Stories about the boat-dwelling men of the night who have cursed the land and come ashore only to feast on men's flesh.
