Britian, A.D. 343. The end of Roman Rule. The Antonine Wall has fallen and order slowley collapses on the northernmost edge of the empire. What little protection Rome has from the Dalriad and Caledone tribes comes from a small post of half-wild legionnaires: the Frontier Wolves.
A young commander is sent to preside over this undisciplined lot at their borderland outpost. But Alexios Flavius Aquila knows his assignment to Castellum was not a promotion. After abandoning a fort in the German province during a barbarian attack, the centurion lost half his men. Were his uncle no the governor of northern Britain, Alexios would not be calling himself a legionnaire at all. Failure and privilege do not recommend the young man to his hardened troops, so survival depends upon understanding these untamed men and earning their respect. With discipline and courage, Alexios too may win the title of Frontier Wolf.
