Sirius Black: a Second Chance (Harry Potter fanfic)

What if Sirius had another chance? Will he choose the same path he once walked or try to change history for the better? I believe that Sirius is the character with the most wasted potential in all of Harry Potter. Hopefully this will be a fun way to explain why. This is a deep dive into HP headcanon with an exploratory look into the nature of magic and the soul. Written for my own enjoyment, may never be finished. I do not own Harry Potter or any of the characters depicted from this franchise.
