Summary
When Nic, a slave in the mines outside of Rome, is forced to enter a sealed cavern containing the lost treasures of Julius Caesar, he finds much more than gold and gemstones. He discovers an ancient bulla, an amulet that belonged to the great Caesar, filled with a magic once reserved for the gods--magic some Romans would kill for.
