Siege

1453. For over a thousand years the walls of Constantinople have protected the capital of the Eastern Roman Empire, the furthest outpost of Christianity. But now endless ranks of Turkish warriors cover the plains before them, their massive cannons trained on the ramparts. No European army will help. Constantinople is on its own, and treachery is in the air. Three people will fight to determine the fate of an empire: the young Sultan, returned from exile and desperate to prove his greatness; a Roman princess sworn to protect her city; and a mercenary captain with a personal score to settle.
