Sometimes she acts kind of like a fool, but at other times she can prove herself to be decently smart. Some notable events with her include at the beginning when she used the Ouija board with Jay, and when she felt Rebecca. Another significant event would be when she fought Piper at the cliffside, running form her to try and survive.
Cameron is the dark haired, blue eyed cousin of Sophie. He's the one who mainly helped Sophie towards the end of the novel. From the first fire scenario Piper caused, he has a burnt hand which he is very sensitive about. Thanks to this hand he is unable to play his precious piano with both, damaging his title as the piano prodigy. Cameron is very protective over Lilias and just thinks Sophie is crazy at first, acting coldy to her.
Piper is a teenager with strawberry blonde hair and sea-green eyes and is described as being very beautiful. She acts very fake towards others, luring them in with her cheerful smiles and sweet facade. It is revealed towards the end of the book that she is actually a psychopath and really desired to kill everybody. She is suspected of putting the needles in her boyfriends eyes, and the reason Lilias tries to kill herself.
