I'm looking for a story I started to read a while back but never finished. In it a man having financial difficulties moves back into the family home with his eldest sister who is in the same boat. The next sister in line also moves in after a bad marriage. Finally the two youngest sisters move in so that all can help each other make ends meet. The man does start to have sex with one of the sisters, but that's as far as I got. I had to stop reading for some reason I don't recall. And now can't remember the story or author. The author, if I remember correctly, was a jumble of numbers and letters. Could anyone help? Thanks.
