Threading the needle

"The Nexusthe 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 beyondhas Shattered, the resultant pulse cascading through the system and leaving Erenthrall decimated, partially encased in a massive distortion.... 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, theyll have to enter a city controlled by vicious bands of humans and non-humans alike, intent on keeping what little theyve managed to scavenge together" --
