Twelve-year-old Nyshell has more than her share of challenges, but that's why she received an implant. By having built-in tutors and other tools piped into her brain, Nyshell and those like her have a shot at succeeding alongside the kids who could afford such enhancements. Normally, the installation of apps into implants is adequately controlled by parents. But in a near-future society still much like our own, parenting can slip. Things happen that shouldn't. And when all a girl wants is to have one friend, even if that friend exists only inside her head, that desire may change the lives of millions...if it doesn't destroy her first.
