I have no idea if that book is meant to be free or not. I also haven't read it. Like you, I was a bit curious about her writings and how she supported her views. So, I hit up Google and that's an example of one of the results. There are quite a few hits, often at .edu domains.

Alas, it will be a little bit before I have time to read it.
