There's something wrong with Willow House.

When author Andrew Whelan and his children, teenager Sarah and ten-year-old Jake, move from Boston to a house in the country, they think it will be a new start. Grieving the loss of his wife in an auto accident the year before, Andrew hopes that the rural setting will help bring them together again and finally allow them to heal.

But the old house hides a terrifying secret, an injustice perpetrated long ago during the time of the Salem witch trials. A restless spirit haunts Willow House, a supernatural force with one thing on its mind.

Soon the family find themselves pitted against an evil entity that will stop at nothing to exact revenge for an age-old grudge.
