Trapped in a world where people can see what others cannot... ...and still no one sees the truth. Fourteen-year-old Mattie Hutchinson is Kavi, a seer. Some of her best friends are living in a parallel dimension, invisible to all but a few. She finds herself juggling between two coexisting worlds, straddling the difficult task of living a normal life in small-town Minnesota and spending time with the Veolish, ordinary people who have been turned into little more than ghosts. She has always been able to hold a balance, but now that her father has been diagnosed with terminal lung cancer, everything is different. Mattie's world is falling apart. But as the dimensions begin to fall into disarray, she and her friends are faced with questions that have dangerous answers. What is Veol? Where has the missing girl in town gone? And who can they really trust?
