When Chloe and her friends get accepted to Hogwarts for a study abroad program, they are swept up into the everyday life of Hogwarts students and all the excitement of the Triwizard Tournament. I'm bad at summaries. The main pairing is Fred/OC and I may add in some more, not sure yet. Takes place during Goblet of Fire, obviously.

Dahlia Aurentius is your average girl when she begins at Hogwarts School of Witchcraft and Wizardry.

A friendship blossoms. What will happen next? I haven't decided yet :P
