Ariantes is a Sarmatian, a barbarian warrior-prince, uprooted from his home and customs and thrust into the honorless lands of the Romans. The victims of a wartime pact struck with the emperor Marcus Aurelius to ensure the future of Sarmatia, Ariantes and his troop of accomplished horsemen are sent to Hadrians`s Wall. Unsurprisingly, the Sarmatians hate Britain - an Island of Ghosts, filled with pale faces, stone walls, and an uneasey past. Struggling to command his own people to defend a land they despise, Ariantes is accepted by all, but trusted by none. The Romans fear his barbarian background, and his own men fear his gradual Roman assimilation. When Ariantes uncovers a conspiracy sure to damage both his Roman benefactors and his beloved countrymen, as well as put him and the woman he loves in grave danger, he must make a difficult decision - one that will change his own life forever.
