How hard do you have to shake a family tree to find out the truth of the past? Fifteen-year-old Rae Kerrigan has never questioned her family’s history. That is until she accepted a scholarship to Guilder Boarding School in England. Guilder is a very unique, gifted school. Rae has no idea what she is getting herself into or that her family’s past is going to come back and taunt her. She learns she is part of an unparalleled group of individuals who become marked with a unique tattoo (tatù) on their sixteenth birthday. The tatù enables them to have supernatural powers particular to the shape of their marking. Both her parents were marked though Rae never knew, as they passed away when she was young and never told her. Learning about her family’s past, her evil father and sacrificial mother, Rae needs to decide if there is a ray of hope for her own life.
