This novel of Roman Britain is told in first person by Quintus Petillius Cerialis, commander of the Roman Ninth Legion and later Governor of Britain. The story opens in AD61 at the time of the bloodbath of the Boadicea rebellion. Cut off and surrounded on a viciously hostile island, the Roman army fights its life with humiliating losses. Later, on his first exploratory mission as Governor, Petillius extends Roman territory by quelling the tribes of the north and founding a fortress at York. The campaign by which he finally outwits the Brigantes and defeats them in the Pennine fastness provides a thrilling climax to a novel which never flags in conviction, in pace and in historical and human interest.
