Harry Potter Everyone Lives AU

Harry Potter: Everyone Lives AU is an ongoing fan fiction series by AidanChase, based on the famous J. K. Rowling's Harry Potter series. The fan fiction has many major parallels with the canon series, and the major changes usually involve altering the mortal fates of characters, like James and Lily Potter, hence the series' title. It is currently hosted on Archive of Our Own and Tumblr. The series began on May 06, 2014, and is still in progress. Completed works include Gryffindor Blood, Harry Potter and the Philosopher's Stone, Harry Potter and the Chamber of Secrets, Harry Potter and the Prisoner of Azkaban, and Harry Potter and the Goblet of Fire, Harry Potter and the Order of the Phoenix, and Harry Potter and the Half-Blood Prince.

Chapter Perspective Variations
The majority of the AU is told through Harry Potter's perspective, as it is in J.K. Rowling's original novels. J.K. Rowling occasionally deviates from Harry's perspective to tell other parts of the story. The AU leaves Harry's perspective far more frequently. Chapters of the AU that do not deviate heavily from J.K. Rowling's original books are often retold through letters between Harry and his parents or from the perspective of an alternate character within the universe.

Trivia

 * Though the story order is parallel to the canon books, there are pieces of canon information that are mentioned earlier in the AU series that were not revealed until much later in the canon books, such as information about character motivations, the war, prophecies, and wandlore.
 * In the original books, Harry frequently refers to adults by their last name. For example, he uses Mr. and Mrs. Weasley rather than Molly or Arthur. This is less common in the AU series; in the narrative text, Harry often refers to adults by their first names, and he even refers to his parents as Lily and James. In dialogue, however, he uses last names, and calls his parents "Mum" and "Dad." Exceptions to this are:
 * Remus Lupin, who is referred to as "Uncle Remus" at first, but eventually becomes "Remus" in narrative and dialogue; during Prisoner of Azkaban, Harry calls him "Professor Lupin" in class.
 * Sirius Black, who is always just "Sirius"
 * Regulus Black, who is sometimes "Regulus" and sometimes "Regulus Black"
