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. And now Roger, the youngest son, has finally come to Italy and proves himself also to be a great warrior and canny politician. The path is not easy, there are enemies at Roger?s back as well as before him, treacheries both secret and transparent to circumvent. 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, with papal blessing, the first true crusade of the 11th century.

1936. Having returned from Abyssinia, soldier of fortune Cal Jardine is convinced by his abhorrence of fascism to travel to Barcelona and help facilitate rival athletic games to the Berlin Olympics. But now he finds himself in Spain as the first shots of civil war ring out; and friendship, love, and political conviction converge to persuade Jardine to stay and once again embroil himself in foreign war. Discovering that the British athletes attending the games are keen to enlist for the fight, Jardine agrees to train them into a professional force. With old army comrade Vince Castellano and his beautiful interpreter Florencia Gardiola by his side, Jardine leads the athletes through the street battles of Barcelona and onto the fighting in the Catalan countryside, acquiring famous friends and effective allies along the way - as well as dangerous enemies. Manfred Drecker is a German communist diehard, who brooks no moral qualms in his deadly determination to see Spain transformed into a socialist state under the rule of the Soviet Union. Having witnessed his trickery and torture, Jardine is already on his guard against Drecker; but when murderous betrayal blights his previous fortune, Jardine will go to any lengths to seek suitable revenge ...
