When the falcon has flown, the mountain lion will charge from the east, and all Byzantium will quake. Only one man can save the empire . . . the Haga!

1046 AD. The Byzantine Empire teeters on full-blown war with the Seljuk Sultanate. In the borderlands of Eastern Anatolia, a land riven with bloodshed and doubt, young Apion's life is shattered in one swift and brutal Seljuk night raid. Only the benevolence of Mansur, a Seljuk farmer, offers him a second chance of happiness.

Yet a hunger for revenge burns in Apion's soul, and he is drawn down a dark path that leads him right into the heart of a conflict that will echo through the ages.
