The Spirit that haunts the willow tree

I do not own any of these characters.

Evan Rosier doesn't believe in rumors or stories without any proof. So when he's told about the rumors surrounding a shack within hogsmeade he doesn't believe them.

Even more so when he hears the tale about a spirit that only appears during a full moon, he's positive the stories are all lies.

But one night during his 5th yr, everything Evan thought changes and he finds himself with a new obsession and some questions that need answers.
