Rome, AD41. Caligula has been assassinated and the Praetorian Guard have proclaimed Claudius Emperor – but his position is precarious. His three freedmen, Narcissus, Pallas and Callistus, must find a way to manufacture a quick victory – but how? Pallas has the answer: retrieve the Eagle of the Seventeenth, lost nearly 40 years before. Who but Vespasian could lead a dangerous mission into the gloomy forests of Germania? Accompanied by a small band of cavalry, Vespasian and his brother try to pick up the trail of the Eagle. In search of the Eagle and the truth, whilst being pursued by barbarians, Vespasian must battle his way to the shores of Britannia. Yet can he escape his own Emperor's wrath?
