The triumphant conclusion to this epic historical trilogy about a Scottish family's rise to power during the Holy Crusades Duncan has returned with his new wife to the fastness of Banvard, to continue his father Murdo's good work in building a powerful and devout community. Even more precious a gift than his wife, though, is the other item that Duncan has brought to the Scottish the Black Rood, the holy Cross of the Crucifixion that Duncan rescued from the clutches of the Knights Templar. Yet the reach of the Templars is long, and soon Duncan and his loved ones find themselves under attack from the Christian Knights. Duncan's daughter Cait is forced to flee, and soon finds herself on a boat heading for the Moorish strongholds of Spain, where she will find herself mired in a battle for religious supremacy which threatens to leave only corpses in its wake. Cait appears to have little hope of survival, but it seems that the pious devotion of her forebears is about to bear miraculous fruit. And the possibility of her survival becomes intertwined with the discovery of the most holy relic of all! In the final part of this enthralling trilogy of historical adventure, Stephen Lawhead delivers an explosive and revelatory climax to this unique religious fantasy quest.
