Kan det här vara Survivor av Octavia Butler? Framför allt etablerar främlingar rang (och något av ett kastsystem) via pälsfärg.
Survivor follows the early contact between the Missionaries, a group of human colonists fleeing a plague on Earth, and the Kohn, intelligent natives of the planet on which the Missionaries have arrived. In particular, the novel focuses on Alanna, the adopted daughter of the Missionaries' leader, as she attempts to prevent the Missionaries' destruction or assimilation at the hands of a dominant local culture. During the course of the novel, Alanna's experiences assimilating and negotiating with the Kohn draw upon her earlier, similar experience joining the Missionaries themselves, and Alanna's ability to interact with the various cultures becomes the key to their survival.
