Plot: People in domes where the ruling class got cybernetic implants that
added to their intelligence/memory. There was some risk involved with the
implant, so some kids don't survive or end up brain damaged in some way.
The main character is a teen boy who has just gotten his implant. He finds
out that someone actually decides whether or not the implant will be
successful, the damage doesn't happen by accident, and one of his friends
is the child of a family that doesn't 'fit in'. He ends up having an
adventure outside the dome. Random other detail, dome-dwellers habitually
remove all their body hair.
