ForeverChild

Three-hundred years into the future...and the world has changed. Among a chosen few, life expectancy is now hundreds of years; these are the forever children, and science has found a way to keep them in a nearly endless childhood. Secure in their giant hives, they have left the outsiders, who must live natural lives, to fend for themselves.
This is the story of Kianno and Seelin, two children who find themselves trading places in this strange new world, one leading the life of a forever child and the other growing up in the anarchy of the outside world. Their lives come together again in surprising and unexpected ways, as they both become involved in a fierce struggle between the two worlds.
