Four Means Trouble (Sirius Black's Daughter)

Indigo is a new student at Hogwarts, starting her first year with her best friend, Harry Potter. Once the duo enters the magical world, they are bombarded with people shaking their hands and asking about their scars. But the two know that the wizarding and witchcraft world is more than silly wand-waving and being famous for having dead parents. Because life is never that simple with Indigo Black and Harry Potter.
