The Roman Republic is crumbling, torn apart by rivalries. Egypt is a wellspring of wealth, but its rulers have squandered their advantage and ended up hopelessly indebted to the protection racket that called itself Rome. Now a woman, as Pharaoh, has a chance to reclaim what Egypt has lost. And a disgraced Roman commander has his chance to reclaim his sword and wield it to build an empire unlike anything the world had seen. Their stories collide in a maelstrom of ancient history, high politics and power.
