The Curious Case of Lucy Day: A Harry Potter Marauder's Era Fan Fiction

Lucille Day sighed as she set down her bags on the front steps of Hogwarts School of Witchcraft and Wizardry. After escaping from her incredibly pure-blooded family in America, she had come here as the only safe haven she could find. She had written to the headmaster, Albus Dumbledore, to ask if she could join the school for her seventh, and final, year of wizarding training. He had accepted her application, and she had finally arrived. She had purposefully come a bit later than she had been expected to, as she didn't want to draw any unnecessary attention to herself. That was her true intention of being here, in a different country, using a different name, to hide. If her parents found her, well, she would be getting a lot worse than a usual scolding.
See, Lucille had a gift. A wonderful, terribly wonderful gift. She could use magic without a wand. This gave her a huge advantage in almost everything she did, for she didn't need her wand to create and do things. Using a wand did certainly make her magic more powerful, but she didn't need one. Her parents had been forcing her to use it in ways she didn't even know she could. Torture, terrible, terrible torture. So she had run. Run from the life of being Alessandra Magnus, the daughter of the most prestigious wizarding family in America, from the burdens and struggles of her daily life, and from the terrible secrets her family hid from the public. For now she was Lucille. Just your normal, everyday witch, Lucy.

Now, with a dark force gathering, Lucy is in more danger than ever. Can she, and her newfound friends, the marauder's, escape from the Dark Lord's grasp, or will she fall into darkness before they can save her?
