Andrea Black — seventh year, Slytherin, 17 — is the kind of girl Hogwarts seems to have been built for. She’s Sirius Black’s niece, Bellatrix’s great-niece, Andromeda’s goddaughter — carrying all that weight and none of the coldness people expect. She’s the school’s golden girl not because she’s perfect, but because she makes everyone else feel a little brighter just by being near them.
