Hadrian's Wall — William Dietrich

It has stood for three centuries at the edge of an empire--a massive structure built to keep the Roman conquerors separate and safe from the barbarians. Now, in the year A.D. 368, a senator's daughter has come to Britannia's shores, a beautiful, enigmatic noblewoman who's destined to be the bride of an ambitious tribune. But Valeria's arrival and mysterious disappearance threaten to unleash jealousy and passion, conspiracies and power plays, and an epic battle between Rome's brutal overlords and the proud Celtic warriors that could topple Hadrian's Wall ... and shake a tired and tottering Empire to its core.
