Book
War at the Edge of the World
First published 2015
Britannia, AD 305. Aurelius Castus, a veteran of the Danubian legions, has been posted to the northern edge of Roman Britain and expects little more than routine frontier duty. When a Pictish king dies in suspicious circumstances, Castus is ordered to command the escort of a Roman embassy beyond Hadrian’s Wall. The mission quickly turns from diplomacy into betrayal and a fight for survival in territory where Roman authority is uncertain.
The adventure unfolds at the end of the first Tetrarchy, when Constantius Chlorus governs the western provinces and his son Constantine is moving toward the career that will reshape the empire. Ross uses Castus’s dangerous journey beyond the frontier to introduce both the military texture of late Roman Britain and the unstable politics behind it: a world in which provincial violence, imperial succession and personal loyalty can suddenly become part of the same conflict.
