My all-time favourite chilling tale is the novel "Harvest Home" by Thomas Tryon. A book that will give you nightmares! A New York couple and their daughter move to a quaint country village in New England hoping to settle into a tranquil existence. They found that the locals were obsessed with ancient pagan rituals and that the village is seemingly controlled by the Widow Fortune, an old woman with a knack for healing. The village has a secret, and its insular villagers are all in on it! Determined to discover what that secret is leads the protagonist to find that some secrets are best left undiscovered.
Harvest Home is a great read for those interested in the horror, suspense, and mystery genre. While it's not the typical blood-and-guts horror story, it is terrifying, largely due to its believability.
This novel was made into an excellent TV mini-series entitled "The dark secret of Harvest Home" starring Bette Davis as the Widow Fortune.
There is even an online study guide available for the novel "Harvest Home".
