The Brin say Robyn's uncanny quickness and stark physical oddities are the devil's traits. Her physical differences are aptly suited to stave off the assailants who hunt her following the killing of a revered Keeper-a death she unwittingly delivered... a death that ignites a war. Driven by a fear of failure and the hope of quelling the spreading chaos, Robyn must return home to Keeper Corax, her mentor and surrogate father, and the one that can restore peace. However, her journey unveils she's a pawn at the heart of a conspiracy. The people compare Robyn to the devil; now she will reveal how right they are.
