Title: The Ilvermorny Champion
Author: Vance McGill
Summary: Instead of Durmstrang Academy, Ilvermorny School of Witchcraft and Wizardry was invited to take part in the 1994 Triwizard Tournament. When Ilvermorny arrives at Hogwarts, Albus Dumbledore is shocked to see the long-thought-dead Harry and Lily Potter appear, as well as the missing Sirius Black and Remus Lupin.

Your comments, if any: In progress and updated fairly often. If you've been interested in any of the America!magic from Pottermore, this author has tried to incorporate a ton of that quasi-canon into this story. The upside - Harry is very zeroed in on Hermione from the get-go. The potential downside - it's a harem fic, essentially, even if Hermione is the focus. But plenty of Lily and Sirius and Remus to go around as well.
