Conn Iggulden, the New York Times bestselling author of the Emperor, Conqueror, and Wars of the Roses series, returns to the ancient world with a ferociously violent epic.

401 BC. In the ancient world, one army was feared above all others. The Persian king Artaxerxes rules an empire stretching from the Aegean to northern India. As many as fifty million people are his subjects. His rule is absolute. Though the sons of Sparta are eager to play the game of thrones . . .

Yet battles can be won--or lost--with a single blow. Princes fall. And when the dust of civil war settles, the Spartans are left stranded in the heart of an enemy's empire, without support, without food, and without water.

Far from home, surrounded by foes, it falls to the young soldier Xenophon to lead the survivors against Artaxerxes's legendary Persian warriors.
