Halo Upon Ripples

The story of MARYSUE GIRL Cathleen Stillwater and her years at Hogwarts. It's a next gen fanfic with only 1 or 2 canons. Slightly AU. Only borrowing the concept of Hogwarts and wizard world, and on other parts can be recognized as a independent story. ][I'll put a tagline here: You never guessed who you'll face off at last, but the ripples mean that there isn't tranquility anymore.
