218 BC. Hannibal’s exhausted army staggers down from the last Alpine pass like a rabble of half-starved savages, the remnants of a once magnificent army that had set out from the Rhodanus with such hope. Now there is no way back. With the legions of Consul Publius Scipio closing fast, Carthage needs its Gaulish allies like never before. But where are the Insubres? Where are the Boii? Where are the thousands of warriors pledged by solemn oath? In the maelstrom of battle, Sphax, nephew of Hannibal, forges a reputation as the scourge of Rome. But will his ingrained recklessness and quest for honour set him at odds with the forbidding genius of his uncle? Only one thing is certain in this winter of winters, a great battle is coming that will decide the fates of Rome and Carthage.
