A Celtic Queen. A ruthless zealot. The terrifying relic that will change the world. - Two thousand years ago the Celtic Queen Boudica waged war against the Roman army. She nearly won, though history cannot explain why. - When Harry Fox uncovers lost documents from Aristotle and Emperor Nero, he learns Queen Boudica used an unearthly weapon to nearly topple Nero's army. And this weapon may still exist. - But Harry isn't the only one hunting for Boudica's relic. A religious zealot with millions of followers is chasing Harry on a path left by a desperate Roman general. A path that winds across Europe and leads to the truth behind Boudica's terrible power. - This is a race he cannot lose, for Boudica's relic threatens all of humanity - unless Harry gets it first.
