When sixteen-year-old Ivy starts a new life in her stepfather's castle in Scotland, she finds that her stepfather's grandmother is implacably hostile and some mysterious spirit in the castle is trying to injure her--and her new best friend is a ghost named Logan.

While awaiting DNA test results that could determine the identity of her biological father, high-school senior Kendall Moorehead and her friends use their psychic abilities against an evil, Civil War-era doll said to have been made by a voodoo priestess.

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.
