Second book in Joshua Palmatier's epic fantasy trilogy, set in a sprawling city of light and magic fueled by a ley line network.

The Nexus—the hub created by the Prime Wielders to harness the magical power of the ley lines for the city of Erenthrall, the Baronial Plains, and the world beyond—has Shattered, the resultant pulse cascading through the system and leaving Erenthrall decimated, partially encased in a massive distortion.
 
The world has fared no better: auroral storms plague the land, transforming people into creatures beyond nightmare; silver-white lights hover over all of the major cities, the harbinger of distortions that could quicken at any moment; and quakes brought on by the unstable ley network threaten to tear the earth apart. The survivors of this apocalypse have banded together in desperate groups, both in the remains of Erenthrall and in small enclaves beyond the city, scrounging for food and resources in an ever more dangerous world.
 
Having survived the initial Shattering, Wielder Kara Tremain and ex-Dog Allan Garrett have led their small group of refugees to the Hollow, a safe haven in the hills on the edge of the plains. But the ley system is not healing itself. Their only option is to repair the distortion that engulfs Erenthrall and to fix the damaged ley lines themselves. To do that, they’ll have to enter a city controlled by vicious bands of humans and non-humans alike, intent on keeping what little they’ve managed to scavenge together.
 
But as soon as they enter the streets of Erenthrall, they find themselves caught up in the maelstrom of violence, deception, and betrayal that the city has descended into—including the emergence of a mysterious and powerful cult calling themselves the White Cloaks, whose leader is known as Father....
 
He is the same man who once led the terrorist group called the Kormanley and brought about the Shattering that destroyed the world!
