I read How The World Works by Chomsky - it's a collection of his radio appearances and whatnot transcribed, so it's all nice n colloquial. I'm thinking Bullshit Jobs next, because apparently it's quite funny and easy to radicalize libs with, which to me at the moment feels more useful than dumping communist theory onto someone that'll write it off instantly because gommulism is when no iphone.
You can find a book that strikes your interest on my party's book publishing site
I can also recommend Moissaye J. Olgin's "Why Communism? Plain Talks on Vital Problems" since it's a booklet/pamphlet written with conveying the "why" of why you should be a Red to the average prole.
