The Brin say Robyn's uncanny quickness and stark physical oddities are the devil's traits. Robyn, a gangly human, stands out among the squat, wide-framed Brin. Her physical differences are aptly suited to staving off assailants who hunt her after the killing of a revered Keeper-a death she unwittingly delivered. The only hope of quelling the spreading chaos and restoring Brin's balance lies with Keeper Corax, her mentor and surrogate father. While journeying to seek Keeper Corax's aid, Robyn confronts truths that shatter her view of the world. She learns humans are a race believed eradicated by the Keepers. She experiences an unexpected arousal when fighting-a dichotomy of compelling and revolting sensations that Robyn struggles to overcome. She unveils the Keepers' parasitic nature-their manipulation of the Brin's life force for power, control and pleasure. Moreover, she discovers Keeper Corax instigates the chaos that threatens to destroy her as well as millions of Brin. The Brin compare Robyn to the devil; now she will reveal how right they are.
