The Sultan, the Vampyr and the Soothsayer

1442: When Vlad Dracula arrives at the court of the Ottoman Sultan Murad II, his life is turned upside down. His father Dracul cannot protect him; he must battle his demons alone. And when the Sultan calls for the services of a soothsayer, even the shrewd teller of fortunes is unprepared for what he learns. 
Meanwhile, the Ottoman Turks are advancing through the Balkans with Vienna in their sights and Constantinople, the Orthodox Greek capital, within their grasp. As Eastern Europe struggles against the tide of a Muslim advance it cannot counter, Western Christendom needs only one prize to overthrow its enemies.
