Legion is a stunning recreation of the life of Roman soldiers at a fort on the Gallic frontier in the late First Century B.C. Centurion Quintus Flavius Rufio returns to Gaul near the Rhine to finish his career with the Twenty-fifth Legion. An invasion by the Germans is imminent, and the veteran Rufio takes command of a century with many recruits whom he must train on the eve of the German onslaught. Rufio's return to Gaul has a wider significance as well. Twenty years earlier, he accidentally killed a young Gallic woman in battle. Still haunted by this, he is confronted by her daughter, orphaned as an infant and now an adult, and his search for redemption takes an unexpected turn in his relationship with her. Legion climaxes with the outnumbered Romans attacking the Germans in a savage battle as the barbarians storm into Gaul in a war of annihilation.

AAt the edge of the Judaean Desert, bandits are menacing the stability of the kingdom of Herod the Great. Alarmed at the unsteadiness of its aging ally and the threat to the security of its gateway to the East, Rome dispatches Tribune Ulpius Crus and a single cohort of the Twenty-fifth Legion to the Judaean wasteland. The tribune asks Centurion Quintus Flavius Rufio to lead the cohort with him to Judaea to establish a temporary Roman presence as a deterrent near the edge of the Salt Sea. Veteran of eastern campaigns, Rufio recognizes that the threat of bandits is an illusion and that Rome faces a far superior danger. He must quickly train his foot soldiers to take to the saddle, for now they challenge a brilliant commander leading a force of the finest horsemen on earth. On the outcome of this confrontation depend the existence of Judaea and the credibility and primacy of Rome.
