Britannia, 43 AD. The last unconquered stronghold of the Celts. A dangerous place of men without fear, soon to face the might of an invading Roman army.
Two young friends from drastically different backgrounds, Prydain and Cassus, are posted to a training cohort under the sadistic tutorage of a battle scarred veteran, Remus. The training is brutal but eventually the trainees set sail for their first campaign… the invasion of Britannia.
The Romans find themselves in strange and unfriendly environment and, as they close in on their quarry, a long held secret will be revealed, culminating in a savage and astonishing climax that affects the very future of Britannia.
