"If Eden fails to mate, she’ll be cut off by the government and thrown to the scorched surface to get cooked alive."
Well, that's officially the worst thing I have ever heard of happening to a single woman. And she's what, a teenager?
"Eden Newman is 17 years old and a “Pearl” -- a minority white girl in a dystopian future in which black people are the ruling class. (If this doesn’t set your teeth on edge already, sounding as it does like the novelization of Paul Kinsey’s “Star Trek” spec script as described in this past season of "Mad Men," then you might want to skip the rest of this article.) This being a Young Adult novel, there’s also a romance component, which takes shape as Eden needs to get “mated” (i.e. married, I guess) before she turns 18, ideally to a black person whose superior genetics will counteract her own when they reproduce (it sounds SUPER ROMANTIC, doesn’t it?)."
"White folks like Eden are not allowed to even be seen in public without darkening their skin -- in other words, blackface is an important plot device."
"Pearls" -- the slur for white people -- are rare and precious, while "Coals" (which has been a legit slur used against black people, in real life) are dirty and common."
If this is a world in which the black people rule, I don't think they would be called anything "dirty and common." Call it a hunch. If white people are so low-class, they would be called something...ruder. That's how brains works. I have to concur with the reviewer that it's hard to think of insulting white slang (other than honkey or white trash).
Honestly, it just sounds freaking weird at best. I don't know what the author is going for here and this kinda comes off as...I don't even know.
