Arimnestos of Plataea has already lived through several lifetimes' worth of adventure, from being a rich man's slave in Ephesus to winning glory at the battle of Marathon against the might of the Persian Empire. But the gods - and the Persians - aren't finished with him yet. As an experienced sea captain - his enemies might say pirate - he has a part to play in the final epic confrontation of the Long War between the Greeks and Persians, the Battle of Salamis. It is a battle where many debts of blood will be repaid, ancient grudges settled, fame won and treachery exposed, where the Greeks must finally bury their differences and fight as one - for against them Xerxes, the Great King, has assembled the greatest fleet the world has ever known, his sworn purpose to brutally extinguish the flame of freedom and make every Greek his slave.
