Jamie Peters plans to spend the summer before her junior year with her nose stuck in a book - not saving lost souls. Usually the girl that blends into the crowd, Jamie's world is turned upside down when a mysterious ghost begins to follow her. But Sophia isn't just any ghost. A hundred years earlier, Sophia's disappearance sparked a national mystery that remained unsolved. Jamie knows the legends surrounding Sophia's disappearance, but she never dreamed she would find out what really happened... or that her family might have had something to do with Sophia's disappearance. Determined to set Sophia free, Jamie blows the dust off her family's past and unearths clues to discover what she must do to save Sophia's soul. She enlists the help of childhood friend - and secret crush - Peter Ashby as she sets off on a dangerous quest to find a missing map. Spending the night in a graveyard, crawling through a dilapidated barn, and staring down the barrel of a gun aren't enough to deter Jamie from helping Sophia. But can she find the answers she needs before another ghost gets revenge on her and Sophia?
