An explosion rips through the Colosseum, and as the smoke clears the
world is changed forever. A new Emperor, spurred on by a riddling
prophecy and armed with a devastating superweapon, stands ready to make
his mark on history. Una, Sulien, and a desperate alliance of slaves,
refugees and criminals, must resist the full power of the Roman Empire
at its most ruthless, or lose everything they have fought for.
