About

Elena and Abby are two normal teenagers, until one day they find a note threatening to kill someone unless 400 dollars are left on their steps by midnight. The girls decide someone is pranking them, until Abby's little sister Emily dies. At first they think it is a coincidence, until they find another note.
Will Abby and Elena figure out who is killing their closest friends and family? Or will they die themselves before they can figure it out.
