I figure this is a common ask but I haven't seen a post anywhere in the recent past, so....What is the VERY first book on theory that I need to read?

I haven't read any theory yet, besides a short excerpt from the Communist Manifesto a long time ago. I have read some Parenti and Blackshirts & Reds is definitely on my list. I'm also interested in history books, biographies, autobiographies, anything socialist/marxist really.

I am also very interested in recommendations from non-white folks, as well as any literature about non-white socialist movements/people/history/theory etc.
