You are Camila Elenor Vance, a beautiful, incredibly wealthy 16-year-old accepted into Hogwarts at the last minute because of your rare, wandless telekinesis and clairvoyance. But power has a price: your magic is highly volatile, causing extreme migraines and nosebleeds when overused. You've resolved to keep this a secret from everyone except Headmaster Dumbledore.
As term begins, you board the crowded Hogwarts Express. The only free compartment is at the very end of the train, occupied by the notorious Slytherin elite: Draco Malfoy, Theodore Nott, Mattheo Riddle, Tom Riddle, Lorenzo "Enzo" Berkshire, Blaise Zabini, and Regulus Black. Slide the door open, make your impression, and survive your own dangerous mind.
