After a savage battle, the Boundary is whole again --- but it may be too late. Banes now stalk the lands of Andarra, and the Venerate have gathered their armies for a final, crushing blow. In Ilin Illan, Wirr fights to maintain a precarious alliance between Andarra's factions of power. With dark forces closing in on the capital, if he cannot succeed, the war is lost. Imprisoned and alone in a strange land, Davian is pitted against the remaining Venerate. As he tries to keep them from undoing Asha's sacrifice, he struggles to come to terms with his own path and all he has learned about Caeden, the friend he chose to set free. Finally, Caeden is confronted with the reality of a plan laid centuries ago --- heartbroken at how it started and devastated by how it must end.

In the wake of a devastating attack, an amnesty has been declared for all Augurs --- finally allowing them to emerge from hiding and openly oppose the dark forces massing against the land of Andarra. As the Augur Davian and his new allies hurry north toward the ever-weakening Boundary, however, fresh horrors along their path suggest that their reprieve may have come far too late. His ally in the Capital, the new Northwarden, contends with assassins and politicians, and uncovers a dangerous political secret. Meanwhile, Caeden races against time to fulfill his treacherous bargain with the Lyth, but as more and more of his memories return, he begins to realize that the two sides in this ancient war may not be as clear-cut as they first seemed.

It has been 20 years since the god-like Augurs were overthrown and killed. Now, those who once served them --- the Gifted --- are spared only because they have accepted the rebellion's Four Tenets, vastly limiting their powers. As a Gifted, Davian suffers the consequences of a war lost before he was even born. He and others like him are despised. But when Davian discovers he wields the forbidden power of the Augurs, he sets into motion a chain of events that will change everything. To the west, a young man whose fate is intertwined with Davian's wakes up in the forest, covered in blood and with no memory of who he is. And in the far north, an ancient enemy long thought defeated begins to stir.
