Do you remember when you were little and you were terrified of the dark? Somewhere deep inside all of us lives a deep and abiding fear of the dark. Our instincts know there are things in the dark, lurking, waiting...terrifying things. For nineteen year old Ava Gibbons, going to spend the summer at her grandparents house was the end to a perfect year. She'd be starting college at Appalachia University in the fall located in the town of Jacob's Fork, WV where her grandparents lived. She'd always loved it in the peaceful mountain town. Jacob's Fork hides a deadly secret...every 60 years there is a string of murders and disappearances in and around the small town. Ava is warned not to go past the fence line in the woods the day she arrives. It's something her grandparents have always told her, something she's always obeyed. She's all grown up now and she's not afraid of the dark anymore. But as she soon discovers, defying her grandparents wishes lead to deadly consequences and a simple truth becomes clear. You should be afraid of the dark and its all she can do to survive it.
