On the mist-shrouded Isle of Hibernia, now known as Ireland, 26 years have passed since the murder of the high king, Fiacha Finnolach. The usurper Elim of Ulster’s promises of peace and prosperity have come to naught, as drought and famine afflict the land. Across the Irish Sea, the Roman Governor of Britannia, Julius Agricola, is met with an intriguing proposition. Fiacha’s son, Tuathal Techtmar, born when his pregnant mother fled into exile, has grown to manhood. He seeks the aid of Rome in avenging his father and becoming High King of Hibernia.

The story begins with a hand curled around another man’s throat. This is Roman justice: Emperor Tiberius first dispatches a traitor—a friend he once trusted with the city—then the man's whole family and all of his friends. It is as if he never existed. Into this fevered forum, a child is born. His mother is Agrippina, granddaughter of Emperor Augustus. But their imperial blood is neither balm nor protection. Rather, it is a liability. Blood is easily spilled or poisoned. So swiftly corrupted. As the aging Tiberius becomes blind to the ignoble end awaiting him, Agrippina sees the future.

In the year A.D. 9, three Roman Legions under Quintilius Varus were betrayed by the Germanic war chief, Arminius, and destroyed in the forest known as Teutoburger Wald. Six years later Rome is finally ready to unleash her vengeance on the barbarians. The Emperor Tiberius has sent his adopted son, Germanicus Caesar, into Germania with an army of forty-thousand legionaries. The come not on a mission of conquest, but one of annihilation. With them is a young legionary named Artorius.

Rome, 107 BC. Quintus Sertorius just lost his father, and he may lose his home. When his rural village is stripped of its political status, he must leave his family to secure their food and protection from inside Rome's cutthroat government. As he transitions from countryman to politician, he's thrust into the middle of a bitter political war…. As Quintus struggles to gain the aid his village so desperately needs, he approaches Gaius Marius, the uncle of Julius Caesar himself.

The year is 104 A.D. Two years have passed since King Decebalus knelt in submission to Emperor Trajan. The recent war between Rome and Dacia was brutal and costly for both sides. The graves of many thousands lie between the River Danube and the gates of Sarmizegetusa.
