I watched Lex Fridman interview Richard Wolff and have spent 2 weeks going hard into marxist and anarchist theories and practice. Working through 2 books, a dozen browser tabs, interviews, etc. It's rare something catches my interest like this (especially non-technical). But I'm really enjoying all the different perspectives and formulating my own fantasy scenarios.
If it hasn't made it onto your list yet, Ursula K. Le Guin's book titled "The Dispossessed" is a great exploration of anarchism in practice through a sci-fi lens
Leninism doesn't quite depart from Marxism really, Lenin expanded upon Marx's ideas and applied them to the evolving material conditions of Tsarist Russia. In a manner of speaking he departed with Marx in the way that Marx thought revolution would occur in developed industrialized nations like Germany and France and not rural agrarian societies like Tsarist Russia. Another thing to note is a lot of what Lenin wrote was scathing and sort of exaggerated polemics against others who he often worked alongside strategically, but argued with for the purpose of directing the course of action correctly. His ideas, the conditions and people he was responding to, evolved over time as well, so it's very important to understand those contexts going in, and this book does an excellent job of synthesizing and condensing some of that well:
