The rewrite as [b:Treason|7956|Treason|Orson Scott Card|http://d.gr-assets.com/books/1316635847s/7956.jpg|2085455] is much better.
An imaginative and well-written book about various branches of science developed to an unheard-of degree by the descendants of rebels on a prison planet. Quite a memorable work. Unfortunately Card rather ruined it in a later re-write under the name Treason.
