The final book in the heart-stopping trilogy that began with Mercenaries. In twenty years the de Hauteville brothers have gone from penniless obscurity to become the most potent warrior family in Christendom: depended on by the Pope, feared by Byzantium and respected by the Holy Roman Emperor. Now, at the head of the tribe stands Robert, who has only one aim: to expand his power by military conquest. But his younger brother, Roger, has his own ambitions. Yet, the loyalty of blood that binds this family of warriors together is still present and it is that, above everything, which will be the catalyst that propels the name de Hauteville to the pinnacle of power, as they undertake the first true crusade of the 11th century.
