A Supernatural Study in Hogwarts

Ilvermorny and Hogwarts have decided to do an exchange program with some of their most promising students. The Winchester brothers and some of their friends have decided to participate, and so has the Shurley family. When the Americans get to Hogwarts, it doesn't take them long before getting to know the local students and making some new friends, one of them being the school freak Sherlock Holmes. And they soon discover they'll need all the friends they can get because something strange is going on at Hogwarts, something that forms a danger to all of them and that they will only be able to fix if they work together.
