The Russian Revolution was a great emancipatory event for the working-class until the Stalinist counter-revolution crushed it. But the real histories of (1) the revolution; (2) those who made it and then fought Stalinism until it killed them; and (3) attempts to understand an evolving Stalinism and USSR, and to build a non-Stalinised labour movement — are all hidden. They are buried beneath both Stalinist and anti-socialist lies. These two books uncover the first two of these histories respectively.
These histories are vital for understanding how the left got to where it is, how we can purge Stalinism from our movement and rebuild an authentic socialism, and how we should think about socialist revolution.
This discounted combination comes with a paper study guide for each of the books. You can also get them in combination with Vol 2, which covers the third of the hidden histories listed above.
