Fay Woodcroft and the Clash of Magic

Fay Woodcroft is a British orphan, completely unaware for the first sixteen years of her life that she is a muggle witch. She is summoned to Hogwarts school of Witchcraft and Wizardry on her seventeenth birthday, and it is much, much more than she expected. When the Clash of Magic is announced, she must prove herself and learn to cope with a spine curling secret.
