Sword of justice

"1367: Europe stands on the brink of total war. Political alliances are beginning to rupture. No state is immune: England, France, the Holy Roman Empire, Milan, Genoa, Venice, Constantinople ... Every mercenary knight for hundreds of miles must sharpen his sword and prepare for battle. But Sir William Gold has other problems. Just to reach Europe, he must capture its most unassailable fortress. He must also protect his liege-lord, the Green Count, from assassins hell-bent on his demise. The balance of power in the West will change. William Gold must trust to hope, and his men, that he lands on the winning side."--Publisher's description
