With Meb safely among her own people, Nazafareen has finally embraced her dangerous fire magic. She is the Fourth Talisman, destined to free the heirs from the wards binding their own extraordinary power. With Nocturne and Solis poised on the brink of war, the choices she makes will decide the fate of mortals and daevas alike. Determined to confront Culach and make amends, Nazafareen goes to Val Moraine, setting off a chain of events that ultimately leads her deep into the perilous wasteland called the Kiln and the faceless enemy waiting there. But the ancient hatred that shattered the world a millennium before is stronger and far more devious than she and her companions imagine. Is the Viper truly dead? And can Nazafareen triumph without facing the darkness that lurks within her own heart?
