I personally became an anarchist without reading a particular book, it was a combination of things that I had read, and Murray Rothbard's For A New Liberty certainly cemented the ideas, but Larken's book was well thought out, and up-to-date so that's what I usually recommend people to listen to.

I still think the old-school guys have useful books, but sometimes the things people like Rothbard said, can be off-putting to people, or give them the wrong idea of what we believe.
