I think it was quite...let's call it unfortunate that the "slur" that the "Others" use to refer to humans and that originated in the continent of "Afrikah" is "monkey". And the "Others" saying "some even look like them" doesn't peticularly help.

Best case the (I am assuming white) author is just oblivious regarding the weird coincidence...

Once I realized that all of the Native Americans were essentially monsters, it was really hard for me to finish even the first chapter. I tried, I really did, but the writing style just rubbed me the wrong way and then the very first chapter ends with these Native monsters ripping out the guts of a living human and eating him. Disgusting and messed up. I usually read grimdark fantasy but that's messed up. 

The MC is supposedly a human who can see the future when her skin is cut. I'm really uncomfortable with self-harm and while this "cassandra sanguine" isn't doing it for the same reasons most people do it, it feels too much like promotion of harmful behaviors to a young audience.
