light reading about the black struggle in usa

i’m looking for light reading recs for my white wife.

I am a black women and recently she’s showed interest in learning more about black history and the struggle that black ppl have had to face in the us. She wants to learn not only for herself but for her future kids who who will be black as well.

I’m looking for something light not too long and is a good intro book. I would really love something that starts talking about the past experiences and connects with modern day problems we’re still facing or the effects that we can still see today

thank u in advance!
