What feminist books do you suggest?

I'd prefer to read about "The Guy's Guide to Feminism" by Michael Kaufmam and Micheal Kimmel.

I feel like a hypocrite for suggesting this, having not actually read the thing myself, only touched upon it during discussion at uni...... but
"Bodies that matter" by Judith Butler, which is about how certain physical characteristics are used to create the idea of gender, and then how gender is created and reproduced (and challenged) by action- "performativity".

As I said, I haven't actually read it yet...... but a brief introduction to the theory in it at uni last year really impressed me.
