Seventeen-year-old Marie has coped with a lot in her young life. But things are getting better, especially when she gets a job looking after four-year-old Amy. At first, her new job seems perfect.

Then things start to change. It seems that not everyone is happy with the new situation. There appears to be someone else in the house—someone who is determined to come between Amy and Marie.

This is a masterful and heart-rending modern ghost story by a popular writer.
