AD 15. The German chieftain Arminius has been defeated, one of the lost Roman eagles recovered, and thousands of German tribesmen slain.
Yet these successes aren't nearly enough for senior centurion Lucius Tullus. Not until Arminius is dead, his old legion's eagle found and the enemy tribes completely vanquished will he rest.
But Arminius - devious, fearless - is burning for revenge of his own.
Charismatic as ever, he raises another large tribal army, which will harry the Romans the length and breadth of the land.
Soon Tullus finds himself in a cauldron of bloodshed, treachery and danger.
His mission to retrieve his legion's eagle will be his most perilous yet.
