In Adelaide Simon's world, people aren't born. They are manufactured and programmed, or skarxed, by The Organization, and their whole life is already chosen for them. Due to a malfunction in the program, Addie isn't limited by her skarx. To her, it's just a suggestion on how she should live, but not enforced like everyone else's. When it comes time for her to have her Praidiss, the ceremony in which The Organization gives you the job that will belong to you for the rest of your life, will she accept her chosen future? Or will she attempt to rewrite centuries of evolution?
