In A.D. 1218, Praetor Gaius Marcellinus is ordered to conquer North America and turning it into a Roman province. But outside the walls of the great city of Cahokia, his legion is destroyed outright; Marcellinus is the only one spared. In the months and years that follow, Marcellinus comes to see North America as his home and the Cahokians as his kin. He vows to defend these proud people from any threat, Roman or native.
After successfully repelling an invasion by the fearsome Iroqua tribes, Marcellinus realizes that a weak and fractured North America won’t stand a chance against the returning Roman army. Worse, rival factions from within threaten to tear Cahokia apart just when it needs to be most united and strong. Marcellinus is determined to save the civilization that has come to mean more to him than the empire he once served. But to survive the swords of Roma, he first must avert another Iroqua attack and bring Cahokia together. Only with the hearts and souls of a nation at his back can Marcellinus hope to know triumph.
