Siren- A Harry Potter based fanfic

Willow Evelyn Peaks is a half blood witch, new to Hogwarts from Ilvermorny. She meets Hermione Granger, Ronald Weasley, Draco Malfoy, Fred and George Weasley, and the famous Harry Potter. She bonds with the golden trio, gets into some trouble, and tries to solve the whereabouts of Sirius Black. But, what happens when small hints of her secret get out? As the years progress, hints become stories, and stories into rumors. Everything starts spiraling out of Willow's hands, and she can't take control of it again. Will she loose all her newly made friends to a small power? Or will they accept her and help her get through it?

I do not own any Harry Potter characters/plot, other than Willow Evelyn Peaks. Requests open to who her love interest may be.
