Roman Britain, AD 44. The land is far from tamed. A puppet king is doing little to calm the hatred of the native tribes.

Fighting is in Optio Horatius Figulus' blood. His Celtic ancestry gives him the toughness essential for survival. That toughness will be tested to the very limit when he is sent on a mission deep in hostile territory. And Figulus knows that, even utterly crushed in battle, their warriors routed and the Druids driven from their hill forts, the tribesmen of Britannia will sooner die than surrender.

Figulus fought alongside Macro and Cato in Simon Scarrow's bestselling Eagles of the Empire series. In INVADER, he stands alone.
