Aubrey Kenzie was ready to get away from Hogwarts. Seven years were more than enough time for her to be spending in a stuffy, albeit magical, school. When Headmistress McGonagall proposed a retreat for some 'House-unity' reason, Aubrey was the first to sign up. Of course, being Head Girl meant that she was one of the supervisors on a seven-hour train ride full of unruly teenagers. And of course, someone had to go missing.
