I recently read some Agatha Christie - Murder in Mesapotamia - I think it was - in which the narrator was female (so the crime and Hercule Poirot's subsequent investigation was seen through her eyes) - and where the interaction between the female characters was a large subplot of the book. I was trying to think of that from feminist perspective at the time.
I've got those 2 aswell, read the bell jar a couple of years ago but would happily re-read. VW I'm a bit intimidated by as I can't imagine she's an easy read and English lit is not my strong point.
As for 'to kill a mockingbird'- I liked that when I did it at school, but now, as a feminist I object to the 'woman lies about rape' aspect of the story. It is perpetuating the myth that this is a common occurrence.
