Feminist literary theory paper book help

Hello, so l'm a senior who is in an English college course at hs. Currently we are working on our final paper in parts and I need a piece that would provide me with an in depth analysis of feminist literary theory. I mean a novel or play. So for example, I thought of Pride and Prejudice, but as I'm reading it, I'm finding it hard to analyze and find certain things. However, other times I feel the complete opposite. Another I’m thinking of is yellow wallpaper but it’s pretty short and this paper needs to be a minimum of 7 pages. Can you guys recommend any novel or play that would truly give me a good grade on this final lol. THIS IS NOT HOMEWORK HELP I JUST NEED A PIECE😭
