Pretty decent overview, especially for the actual moments of the October Revolution, but I don't see how that's relevant to the USSR's history and economic model following the revolution, the split of Trotsky from his temporary adherance to Marxism-Leninism back into petite-bourgeois menshevism, or Stalin's merits/demerits. The sources I provided as a whole go far more in-depth, and go far beyond 1917.

Not really sure what you're trying to say here, other than "actually existing socialism bad."

As a side-note, the Prolewiki version of Ten Days that Shook the World is also a nice option for those who prefer that format while reading on mobile!
