To outsiders, Hannah has it all. She's taking college classes, holding down a fun job, and dating one of the most sought-after boys in town. But Hannah has secrets-secrets about herself and her past, the people she's hurt, and the people who want to hurt her. When an unthinkable tragedy blurs the line between the natural and the supernatural, Hannah finds herself trapped between the world of the living and the dead. As a spectator of the only life she's ever known, Hannah watches her own murder investigation from a different dimension of life-a place where no one can see or hear her aside from a mysterious boy named Art. Will Art be able to help Hannah uncover what is keeping her in limbo? Or is there more to the situation than either one of them dares to imagine?
