Harry Potter: The Invincible Scholar

This book is also known as Hogwarts: Everything Comes in Threes.

1. Plot: Alan Harris is reborn into the HP world and attempts to reform wizarding education and break the Statute of Secrecy—the final boss is not Voldemort, but another character from the original series.

2. Style: This is not a true system novel. In keeping with the HP style, the story becomes darker with each book.

3. Features: Everything comes in threes. J.K. Rowling used 7 as a special number, but in this story, 3 is a magical number. All things return to the cycle; events are cyclical, and in the river of time, everything has a cause.
