Northern Britannia, AD 182. The Tungrians have survived one battle but now face the wider consequences of frontier war. Marcus Valerius Aquila continues to hide inside the army while the province prepares for renewed attacks from tribes north of the wall.
The regiment must hold discipline under pressure from raids, ambushes and Roman commanders with their own ambitions. Marcus’s need for concealment competes with his duty as an officer, because every act of courage risks drawing attention to the man he really is.
