An epic battle of the Reconquista; a personal struggle to survive; a fight for glory.War is brewing, and the Pope has summoned a crusade. The nations of Christendom are rallying to fight the Almohad caliphate, but they are a formidable foe.Meanwhile, behind Moorish lines, a fortress held by Castile is under siege. As the siege falls, a knight is lost. Arnau leaves on a dangerous, near-suicidal quest to save him, a new squire in tow.In the heat of the sierras though, things are not as they seem. War is coming to Iberia and all will be tested. Arnau's sword arm will need practice, as will his mind.
