If you want to learn about the Russian Revolution, the gold standard is the History of the Russian Revolution by Trotsky. Additionally, Trotsky's Lessons of October is a shorter piece that makes puts the victory of the Bolsheviks in it's proper political context and makes clear that it was a genuine struggle Lenin had to lead to win the RSDLP(b) over to taking power in the first place when he returned from exile.
There's also John Reed's 10 Days that Shook the World that's good for the Russian Revolution, the movie Tsar to Lenin, the movie Reds (about John Reed's life).https://www.marxists.org/archive/reed/1919/10days/10days/
Post revolution, the fight between the Left Opposition and the Stalinists is really essential to understanding the whole course of what happened in the Soviet Union, how it degenerated, and ultimately the counterrevolution in 1991. Again, Trotsky is your best bet, and Third International After Lenin and Revolution Betrayed are very good.https://www.marxists.org/archive/trotsky/1928/3rd/index.htmhttps://www.marxists.org/archive/trotsky/1936/revbet/index.htm
