In Orpheus Chanson's world, the human brain has been mapped and patented, and geniuses like him are no longer born or honed through hard work. Instead, only the most priviliged sect of society can purchase and use ASAs, or Acquired Savant Abilities. However, Zimri Robinson, a natural musical prodigy, is a lowly worker at a warehouse. For her, making music is illegal, although she finds time to, even with her grueling schedule and grandmother's illness. Orpheus is destined for greatness; Zimri is not, and their paths were never supposed to cross. But sometimes, rules are meant to be broken. -- adapted from book jacket.
