Diversity in literature, especially Young Adult literature, had been exploding over social media lately. That’s not to say diversity in fiction hasn’t been an issue prior to Twitter getting its hands on it, it’s just now openly available to everyone.
I’m not just talking about slapping on a “foreign sounding name” to a background character, or changing the description of a minor character’s skin to read “dark” or “ebony”. Write a story featuring a person of color (POC); make the main character POC, make the love interest POC, make everyone POC if you really want. But include more than just white and black.
