A Planet Called Treason

The families on the planet Treason have for a long time been separated into warring clans. Yet each family is using its own special products to help barter for much-needed iron. Lanik Mueller, whose family is able to reproduce body parts, finds himself unable to stop growing parts. As this disaster takes him on a journey across the planet, he develops a plan that will help unify the families.

Orson Scott Card's second novel (his fourth book to be published). It faded out of print, then Card made some major revisions/rewrites and republished it in 1988 under the title Treason.
