Hi! I'm Nikki Johnson but everybody knows not to call me by my real name so I'm known as NJ. Yes I am Jack Johnson's little sister but it doesn't really matter because I haven't talked to him in a year since him and our best friend Jack G left me for an event called Magcon. Ever since they left me trouble found me and let's just say I've got quite the reputation with guys and the police. But forget about that and just read the book.
