A Treatise on Harry Potter, the Mary Sue slash Gary Stu

Harry's closet friends, with some modifications (due to setting this in my own HP rewrite's future), sit down together to contemplate the question of how much of a Mary Sue Harry is portrayed as in the novelizations of his time at Hogwarts. This fic can stand alone, you need not read any of my other works to understand it. WARNING: Occasional Fridge Horror inside.
