I've skimmed through the library and it wasn't there, I swear.

It was a fic where Harry goes to another universe because the sword of gryffindor malfunctioned or something while he was at aunt marge's (I think).
And in this universe he was the most infamous deatheater and he gets captured and brought to a Ministry cell. Then his family visits him and I remember that he had a sister but I havent read further. Please help me find it, thanks.

Do remember that the libraries have more stories then what is shown on the first page, using the search option would not hurt either.

 

Thanks *embarrassed face* Probably didn't notice it.
