The obvious choice would be something like Orwell's 1984, but I also think Animal Farm would also be a good enough choice.
One about the dangers of full-on government control and allowing them to censor everything while also turning you aggressively nationalist against everyone else. The other about how one person in a revolution will try to elevate their group to being in full control and taking advantage of the people after said revolution, thus making everyone else's lives worse than before. At least that's what I got out of those books.
Also, side note, I really enjoy the original animated Animal Farm movie and the trailer for the new version looks like if you tried to turn WWII into a cringey kids film. That level of stupidity and unawareness of everything the source material stands for. It looks absolutely atrocious. Disgusting. I refuse to acknowledge it as anything other than something that would cause Orwell to come back to life just to weep at how they're massacring his book with their horrific adaptation. Apparently it was so bad that Netflix dropped the rights to it.
Oh boy! Can't wait for an Animal Farm adaptation where the pigs are super nice to everyone and instead of fighting for freedom, they have a nice afternoon tea session with the farmer and he agrees to give them the farm. Also for the parts where Boxer gets injured and eventually sent to the glue factory to be replaced with nothing because death surely won't be in an adaptation of a book where death and sacrifice isn't a close to being a central point in the very beginning of the book.
