Invaluable. Unsummarizable. Read this as soon as you possibly can.

I think if I had no experience with social justice activism or feminist authors, I would be confused by some portions. If you don't have either background, it's still worth the read. You can choose your own adventure: 1) Go into it with determination like you're cramming for an exam, Googling the basics of any authors/phrases that are new to yon, or 2) expect that you'll have to skim over those authors/phrases, and patiently infer the context the best you can while Smith builds each chapter up. She is very thorough, so I think either approach would work.
