Alexa Carter - The Philosopher's Stone

Alexa Carter knew she was a witch from the get-go - both her parents and her adopted parents had been. But when she goes to Hogwarts, meets the Boy Who Lived, and uncovers secrets about both herself and the castle, she know's it's not going to be quite the year she expected, with three-headed dogs and Quidditch, who knows what's in store for Alexa and her friends?
