A Hogwarts Exprience

Myra Riddle, a first year french mud - blood witch, starts Hogwarts after Snape becomes headmaster. Myra instead of paying attention during any lesson, she listens to music. She never does her work and is a bit of a troublemaker. Lily Luna Potter (Harry Potter and Ginny Weasley's youngest child) is also starting her first year, and Myra has confused feelings about her. Myra does befriend Hugo Weasley (Ron Weasley and Harmione Granger's youngest child). It's hard for her to hang out with Hugo, considering he is Lily's cousin. There is one secret about Myra that no one knows, but will explain almost all her characteristics and how she doesn't pay attention but is great at magic. Also this has some characters from Supernatural, like Dean Winchester, Sam Winchester, and maybe Castiel.
