Kathryn doesn't like Colorado. She's a bright girl from California and can't believe that her mom dragged her here to live with her new step-dad Max and her step-brother Nacxson. What kind of name is that anyway? When the new boy comes to town things start to change. She learns how her dad ran from home and how he ran from her mom. But hey, Kat should know by now that's Pure Instinct for her kind. Shape shifting is never easy.
