Pride and Prejudice variation. Elizabeth sets up a 'penny savings club' and gradually all the sisters join in. I can't be certain if they are estranged from either parent but I think they are.

I read this in the last few years. I can't remember anything more than Elizabeth had this 'penny saving club', I think Edward Gardiner helped with it, and that eventually all the sisters joined it as well. I think that is was so that the girls would have something for if/when Mr Bennet died.
