Glory. Death. Well-born Athenian cavalry officer Kineas fought shoulder to shoulder with Alexander in his epic battles against the Persian hordes. But on his return from the east to his native city, he finds not glory but shame - and exile. With nothing to his name but his military skills, Kineas agrees to lead a band of veterans to the city of Olbia, where the Tyrant is offering good money to train the city's elite cavalry.

September, 1356. Poitiers. The greatest knights of the age were ready to give battle. On the English side, Edward, the Black Prince, who'd earned his spurs at Crecy. On the French side, the king and his son, the dauphin. With 12,000 knights. And then there is William Gold. A cook's boy - the lowest of the low - who had once been branded as a thief. William dreams of being a knight, but in this savage new world of intrigue, betrayal and greed, first he must learn to survive.

Arimnestos is a farm boy when war breaks out between the citizens of his native Plataea and their overbearing neighbours, Thebes. Standing in the battle line for the first time, alongside his father and brother, he shares in a famous and unlikely victory. But after being knocked unconscious in the melee, he awakes not a hero but a slave. Betrayed by his jealous and cowardly cousin, the freedom he fought for has now vanished, and he becomes the property of a rich citizen.

Vaelin Al Sorna is a living legend, his name known across the Realm. It was his leadership that overthrew empires, his blade that won hard-fought battles - and his sacrifice that defeated an evil more terrifying than anything the world had ever seen. He won titles aplenty, only to cast aside his earned glory for a quiet life in the Realm's northern reaches. Yet whispers have come from across the sea - rumours of an army called the Steel Horde, led by a man who believes himself a god.

Arimnestos of Plataea grew up wanting to be a bronzesmith, like his father. Then, in the chaos of war, he was taken to a city in the Persian empire and sold as a slave. To win his freedom he had to show that he could fight and kill. Now, to preserve that freedom, he must kill again. For the Persians are coming. A vast army sent by King Darius to put down the rebellious Greeks and burn the city of Athens to the ground. Standing against them on the plain of Marathon is a much smaller force of Athenians, alongside their Plataean allies. To defeat such overwhelming force seems impossible.
