Written in Red (The Others, #1)

Humans, Simon reminded himself. He adjusted the wire-rimmed glasses that he didn’t need for vision but thought made him look a little gawky and more approachable. Call them humans when you’re in the store. That way you’re less likely to use the slur when talking to an employee. It’s hard enough to find help we can tolerate. No sense driving away the ones we have by insulting them. The word had traveled across the ocean from Afrikah, where the Liongard referred to humans as hairless, gibbering monkeys. After the terra indigene in Thaisia saw pictures of monkeys, they adopted the word because it fit so many of the humans they encountered.

This is so weird and offensive, and I'm surprised no one else has apparently noticed it.
