Admittedly, me being a intercultural speech major made me apprehensive at first as well. My thought when first seeing the cover was "Oh lord... This is going to go wrong in so many ways."
was pleasantly surprised however, as the incorporation of the tribe into society was handled pretty okay for someone who may not know the complexities and toughness the situation actually is.
What I was worried about primarily was ethnocentrism. Not necessarily racism, or the dehumanization of tribal people, but the kind where their culture is seen as less sophisticated than industrialized societies. My fears came true to some extent because of the guy who invited Qaltaqa but that was subverted by the brother (Aqnam maybe?).
I'm an anthropology student so I was a little apprehensive about this one, but while I do have a few minor issues with it, overall I was pleasantly surprised.
The author probably doesn't have any anthropological training, so I think s/he did remarkably well showing cross-cultural interactions.
