The Forgotten Potter

Kendra Potter wasn't a household name in the Wizarding World. No one felt pity or remorse when they heard the name. In fact, no one had ever heard of a girl with such a name before.
Kendra Snape was raised by her loving father Severus and was homeschooled until her fourth year.
What happens when a girl who has never been heard of before comes knocking on the doors of Hogwarts? And will anyone notice that if you look very carefully into her emerald green eyes they have a certain shimmer... A shimmer that's only ever been seen once or twice before...
