A Certain Slant of Light

I wonder if it took that long for Civil Rights books to make an appearance because of it being "appropriate" or not (for lack of a better word) to write kids' books on those topics. But now, we've already seen acclaimed books for teens like The Hate U Give written about very recent topics, so I wonder if children's books will follow suit. There are many more voices than there used to be, and publishing is certainly more diverse (though it has a long way to go still).
