Brigantia

"Ad 100: Britannia. The edge of the Roman world. Flavius Ferox is the hardbitten 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 brutally murdered in a latrine at Vindolanda fort, and Ferox must find the killer. As he follows the trail, the murder leads him to plots against the empire and Rome itself, and an old foe gathering mysterious artefacts in the hope of working a great magic. 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, and the bitter power struggle among the Brigantes, the great tribe of the north."--Provided by publisher.
