So here is an embarrassing admission: I had believed that this was fiction. I thought it was about an imaginary sister of Shakespeare. Turns out, no. It's a critique of literature and women's place in literature through 1920.
I'm making efforts to educate myself on feminism and the women's movement. Yes, I think there were some good points. But really could not figure out how deciphering the rambling sentences was worth while. Not being a specialist in 1920s literature I didn't know most of the writers she referenced. I could hardly stay awake, in fact, I didn't stay awake. It took me more than a week to get through 109 pages!
