Feral by Brian Knight

He comes when you're sleeping.  He is the reason you're afraid of the dark.

After years of living as a prisoner of the fairytale monster that killed her mother, Charity has escaped, but the Bogeyman wants her back, and he will not stop until he has her. There is only one safe place for her now, a haunted place called Feral Park, but the price of safety will be more than her innocence ... it will be her soul.
"FERAL is a haunting, genuine fusion of horrific fantasy and the fearsome dreads of present-day life.  FERAL bites hard and doesn't let go."  Tom Piccirilli, author of Midnight Road
