They fought against almighty odds at the very edge of the known world – and lost. Ten thousand legionaries are all that are left of a once powerful Roman army.

In the first century B.C., trapped in Parthia by Crassus's failed invasion, the legionaries that survived are captured and marched to the edge of the known world. Abandoned by Rome, these men are the Forgotten Legion. Among them are three friends, Brennus the Gaul, Tarquinun the Etruscan soothsayer and Romulus, a runaway slave and the bastard son of a Roman nobleman. All men with troubled pasts and united in their hatred of Rome, they never stop dreaming of Freedom. Together they must face the savage tribes that surround them as well as the more treacherous enemies within the ranks of the legion itself. Their character will be tested to the utter limit as they struggle to find a way back to Rome. Meanwhile, Fabiola, Romulus' twin sister, tries to maintain hope of her brother's survival while fighting for her own. Freed by her powerful lover but beset by enemies on all sides, she must travel to Gaul to find her lover, the right-hand man of Julius Caesar. But in Gaul, her lover is fighting for his very life against Vercingetorix, whose rampaging army threatens to destroy all who rally around Caesar.

Together these characters, whose lives are intertwined and their stories interwoven, bring to life an truly epic story of the late Roman Republic and the ancient world in which it thrived.
