Gaul during the final years of Commodus’s reign. Marcus Valerius Aquila and the Tungrians are sent to deal with an outlaw whose violence threatens Roman authority and provincial order. The mission appears straightforward only to men who do not know the politics behind it.
The pursuit through Gaul exposes corruption and divided loyalties inside the imperial system. Marcus is forced to recognise that the chaos shaking Rome can reach even stable provinces, turning local unrest into another front in his struggle against imperial betrayal.
