Fanfiction: A Marauder's Plan

Fandom: Harry Potter
Summary: Alternate Universe based on prompt 'What if Sirius hadn't run away to somewhere sunny after escaping Hogwarts but stayed and tried to make Harry's wish of a home come true?' Covers alternative 4th Year/Goblet of Fire and therefore does not follow canon religiously.
Pairings: Harry/Hermione is the main pairing. All others are surprises so read at your own risk - although I will say there are a number which follow canon.
Tropes/Cliches/Fanon: Independent!Sirius, Manipulative-but-well-meaning!Dumbledore. Plays with fanon concepts of Ancient and Noble Houses, Potter wealth and status, Super!Harry.
Content warning of references to child abuse (neglect, emotional - Harry; physical, emotional - Sirius) in early parts, references and discussion of grooming and rape/dub-con/sexual contact by an adult with a minor (not Harry) in the last two parts of the fic. Please consider your personal triggers and keep yourself safe. Character deaths abound.
Author's Note: The story that has taken me four years, 87 chapters and over 850,000 words to complete.
