Eu também estava procurando por muito tempo e achei (por acaso). Chama-se " Vítima da Queda " (site de fanfiction adulto).

As to the other alternative, I have found that Mr Flourish of Flourish and Blotts bookshop is renting a small flat above his shop in Diagon Alley. I have been in correspondence with him and he seems to be quite taken with the idea of your living there. I assume he remembers you as a child. He has also mentioned that he would be happy for you to work for him on weekends to pay for your room and board.
