Princess of the Blacks

Charlus Potter the Boy-Who-Liv... WRONG! Artemis R. Black was born a Potter, but with her brother mistaken as the Boy-Who-Lived she is abandoned. Rescued by her Godfather, Sirius Black, she becomes the Black Heiress, a perfect Black alongside her sister, Susan Bones, the Bones Heiress and her cousin, Nymphadora Tonks. How will the Potters react? AU, duh! Slytherin!Fem!Harry.
