Romulus and Fabiola are twins, born into slavery after their mother is raped by a drunken nobleman on his way home from a good night out. At 13 years old, they and their mother are sold: Romulus to gladiator school, Fabiola into prostitution, where she will catch the eye of one of the most powerful men in Rome, and their mother into obscurity and death in the salt mines.

In the First Punic War, the Roman legions defeated and humiliated Carthage, their only serious rival for power in the Mediterranean. Now a brilliant young Carthaginian general, called Hannibal, is out for revenge.

As winter approaches in 74 BC, few travellers are abroad. But one man is making the long and weary last stage of his way home.

He is skilled, hardened in battle, a sophisticated fighter. Spartacus.

Thomas of Hookton is one of these archers. But he is also on a personal mission: To avenge his father's death and retrieve a stolen relic.
