After the events pictured in "An iron destiny," the protagonists must deal with a world where iron and magic returned to human lives. A world in war is the new scenario where humanity, sidhe and an ancient enemy forgotten in the sea of centuries, fight to win the control of the two worlds for their races. Cristina, Jonathan and Joab face tremendous changes and perils to emerge, maybe, as the heroes they are supposed to be. But faeries histories sometimes end with tears, pain and death.
