I wrote this with some of my friends, it's a fanfiction series called Chronicles of House Black about the Black sisters. We're working on Part 3 right now, but this document has Parts 1 and 2, The Hogwarts Years and The Gloomy Hollow. Also, just a disclaimer, this has nothing to do with the fanfilm Sisters of House Black.
Blurbs:
Part 1: Chronicles of House Black: The Hogwarts Years is a fanfiction detailing Andromeda, Bellatrix, and Narcissa Black's lives at Hogwarts, alongside the backstories of the Mirror of Erised and the Philosopher's Stone, the Ministry of Magic's ties with Hogwarts, and the early years of side characters of the main series such as Lockhart, Quirrell, and Trelawney.
Part 2: The sequel to Chronicles of House Black: The Hogwarts Years, The Gloomy Hollow continues the Black sisters' story across the First Wizarding War, and explores the story of the Order of the Phoenix, as well as Lord Voldemort and his relationship with the Death Eaters, Quirrell's journey into the dark side, and Dumbledore and McGonagall's tenure at Hogwarts, while following the events leading up to the attack at Godric's Hollow.
