Freak by Sophie Stern

Fate smiles upon the wicked.
Isla:My entire life has been one complication after another, and then three new kids roll into school acting like they own the place.They don’t.They don’t know anything about Fate High, or Fate, or me.They definitely don’t know what I’m really like.They don’t know the deep, dark secrets that keep me up at night, but something tells me that they want to.And they aren’t going to stop until they get what they want.
