The last thing thirteen-year-old Charly Pederson expects to do is meet a ghost when she, her mother and sister Nikki move to P.E.I. to live with Grammie after her parents' divorce. Charly knows something is up with that old, abandoned house on Northumberland Strait the day that four of them break in and snoop around. While the other kids are satisfied to stay out of the spooky house after that, Charly feels drawn back to the place and knows she has to return alone. She does return and is swept into a time-traveling adventure during which she makes the most unlikely friend – a woman who’s been dead since long before Charly was born.
