Athenian Steel: Roman Annihilation 423 BCE (The Hellennium)

In an ancient world of beauty and brutality, a deadly renegade from the stars will cause some men to rise and others to fall, reducing would-be empires to ash and dust. 

ROMAN ANNIHILATION 423 BCE, comprised of chapters from the original version of Athenian Steel, sees the Athenian general Demosthenes leading a Greek army up the Tiber to assault Rome in 423 BCE, long before Rome's ascendance. His mysterious star-born ally Thalassia, meanwhile, infiltrates the home and heart of a Roman Senator.
If you have not read Athenian Steel, then ROMAN ANNIHILATION serves as an excellent introduction without spoiling the (much-changed) plot of the full-length. If you have read it, then here is an 'alternate vision' of what might have been.

Fear not: Rome will face annihilation again in Book III of the series!
