Who could be the author of the 'Harry Potter finds a magic book' fanfiction?

Well, it could be that the magic book is sentient and starts to communicate with Harry. It could offer him advice on how to defeat Voldemort in a completely new way, like revealing a long - forgotten prophecy.

He might be really confused at first. Harry Potter comes from a world of magic and wizards, and the Avatar world is so different with its own unique cultures, bending abilities and spirits. He could be intrigued by the new concepts and might start comparing the magic in his world to the powers in the Avatar world described in the fanfiction.

Well, it could lead Harry to master the Appari skill quickly and use it to solve some urgent problems.

In this kind of fanfiction scenario, Snape might initially be conflicted. On one hand, he has his long - standing dislike for James Potter, Harry's father. But on the other, his sense of duty as a Hogwarts professor could kick in. He might reluctantly start to heal Harry, all the while muttering under his breath about how much trouble Harry always seems to get into, just like his father. Then, as he heals Harry, he might start to see some of Lily, Harry's mother, in him and soften a bit.

It could expand his understanding of magic. Since fanfictions often explore different aspects of magic, he might learn about new types of magic that he hasn't encountered before. This could be something as simple as a new way to use a wand or a more complex magical theory.
