James Potter x Reader. Alone. Thats what Cassie Carlyle was. She was alone. She'd been alone, she was alone, and she would be alone. Cassie was a transfer to Hogwarts. Sorted into Ravenclaw before the year even started. But life changes for Cassie when she meets the marauders. As cliche as it sounds, Hogwarts changes her. For better or worse, she can't quite tell.
