Torrin Gray is deficient, and no one will let him forget it. Immune to the radiation energy from otherworldly rifts that killed most of the population, he's incapable of harnessing its power like the majority of survivors and must work as a lowly boneforger, supplying super soldiers with weaponry as they explore new rifts and battle vicious parabeasts within. But Torrin's life is upended when he witnesses a horrific crime and gains an unconventional ability that could level the playing field.
