Harmionyfan
Four undercover demigods - Hermione, Draco, Luna, and Neville - have been faking their Hogwarts lives for years. Assigned false identities by the Olympians, they've played their roles... until Voldemort pushes too far. When the final battle looms, the masks drop - and chaos, dark humor, knives, and divine-level sass explode across the Great Hall.
