In a lonely Illinois cemetery one cold October night, teen ghosts recount the stories of their deaths in different time periods, from 1870 to the present, to sixteen-year-old Mike, who unknowingly picked up a phantom hitchhiker.

The haunting starts even before Sophie arrives on the Isle of Skye to spend the summer with her cousins, but when she arrives she finds a house haunted by the ghost of a girl who attended school there a hundred years ago, as well as cousin Rebecca who died young and is never mentioned by her family--and she must somehow solve the mystery of the frozen Charlotte dolls before the whole family is destroyed.
