For over a thousand years, the medieval city of Constantinople has been the jewel on the crown of the Roman Empire. Now, the once-mighty metropolis is broken down, with its defensive walls in shambles. Long have the neighboring Turks wanted to claim the city, and Mehmet—the impetuous new Turkish sultan—thinks he and his legions might finally have their chance. In defiance of his late father’s advisors, Mehmet vows to be the first leader in a millennium to wrench Constantinople from the Christians. He is determined to take the city from the weakened but beloved Emperor Constantine—even if he loses his throne and his life in the process.
