The craziest part of Insanity is not simply that you're going insane ...no, it's that you don't know that you are. It's been months since Aria's best friend, Kelly Mortin, has been brutally murdered by some sick human being who thinks its ok to tare at women's neck in the middle of the night (or at least that is what everyone else seems to be advertising. ) When Aria begins to see her 'dead' best friend she starts to believe that she is losing her strong grasp on reality . Will Aria succumb to the Insanity eating away at her or will she snap out of it before her time runs out?
