AD 61. Britannia is divided.

The rebel horde has been defeated. But the leader, Boudica, and her remaining warriors are still at large. With them is the eagle standard of the Ninth Legion, taken in ambush, flaunted as proof that Rome can yet be beaten.

The embers of rebellion are still glowing . . .

The toll has been heavy, with countless men lost, and major towns in ruins. The bodies of the dead are strewn across the streets. And for Centurion Macro, there is the scarring knowledge that his mother perished in the attack on Londinium.

As Macro's heart burns for revenge, he and his comrade-in-arms Prefect Cato are tasked with hunting down the remnants of the enemy army. There can be no peace until the queen is captured or killed. And Roman honour will only be restored when the eagle standard has been recovered.
