Befriending the Werewolf

When a fifteen year old girl suddenly appears in the middle of the Hogwarts corridors unconscious, everyone's confused. No one can apparate on Hogwarts ground, it was supposed to be impossible. But when the girl wakes up, everyone realizes that there's more to this than they thought: turns out that this girl is from America, where there aren't supposed to be any witches or wizards, and she's been labeled missing by every newspaper and TV channel.
Was this a kidnapping, or maybe a practical joke played by somebody? Victoria, the missing girl, doesn't care either way. She wants to stay at Hogwarts, where everything is magical and mysterious, even though her strict parents demand she returns home at once. But Victoria has befriended a group of girls her age, and is determined to do the same with the school troublemaker, Teddy Lupin.
Will she be able to stay, or will her parents make the journey to take her home at once. And will Teddy Lupin become her friend, or will she be shut out.
