From bestselling historian Adrian Goldsworthy, the final book in his authentic, action-packed trilogy set on the frontiers of the Roman Empire.

AD 117: BRITANNIA. Roman centurion Flavius Ferox is trying to live a quiet life of dignified leisure, overseeing his wife's estate and resisting the urge to murder an annoying neighbour - until someone else does it for him.

Dragged back into a life of violence, Ferox finds himself chasing raiders, fighting chieftains and negotiating with kings. Under the new emperor, Hadrian, the whole world seems to be changing: old friends are now enemies, enemies claim they are friends, and new and deadly threats lurk in the shadows.

When Hadrian himself comes to Britannia to inspect his great wall, war erupts suddenly. Ferox is the only one who can save the emperor - but with his family, and his own life, in danger, he must first decide whose side he is on.
