The Missing Black

Usually people think that Sirius Black had one brother, Regulus, but they are wrong he had a sister too. A sister he was extremely over protective of ever since an incident involving Bellatrix and the Cruciartus curse. This girls name is Cassandra Black and she is finally escaping that stupid house and getting to go to Hogwarts. But while there she meets a very handsome boy named Tom Riddle who isn't supposed to be there. A boy that her brother doesn't like for a reason she doesn't know. For the first time she and her brother will be separated and it might just be fatal. Will Cassandra find true love with Tom and join his army, despite her brother's protests? Will she be able to become an animagus too? What house will she be sorted into? This story is all about Cassandra's adventures with the second year Marauders and her best friends Lily Evans and Juliette Lupin, Remus's half sister.
