Molruh’s campaign spreads across Eastern Arn as the balance of Arca begins to shift toward war. While searching for the second Boshio, Ayan meets Kaya and their lives become bound together in ways neither of them can yet understand. But when Kaya is taken and returned without her children, a secret is set in motion that will haunt them all. As the IAA are slaughtered and Mya risks everything to confront Molruh, Ayan is forced into a battle on multiple fronts: against his enemies, against fate and against truths being kept from him. With loss closing in and unseen hands shaping the future, an army no one can see is already moving into place.
