In 950, Ireland, England, and France were helpless against the ravages of the seagoing Vikings; the fierce and strange Hungarian Magyars laid waste to Germany and Italy; the legions of the Moors ruled Spain and threatened the remnants of Charlemagne's vast domain. The papacy was corrupt and decadent, overshadowed by glorious Byzantium.

Yet a mere fifty years later, the gods of the Vikings were dethroned, the shamans of the Magyars were massacred, the magnificent Moorish caliphate disintegrated: The sign of the cross held sway from Spain in the West to Russia in the East.

James Reston, Jr.'s enthralling saga of how the Christian kingdoms converted, conquered, and slaughtered their way to dominance brings to life unforgettable historical characters who embodied the struggle for the soul of Europe.

From the righteous fury of the Viking queen Sigrid the Strong-Minded, who burned unwanted suitors alive; to the brilliant but too-cunning Moor Al-Mansor the Illustrious Victor: to the aptly named English king Ethelred the Unready: to the abiding genius of the age, Pope Sylvester II - warrior-kings and concubine empresses, maniacal warrior and religious zealots, bring this stirring period to life.
