The Nightmare World - JG Faherty

Twenty-five years ago, Officer Robert Navarro vanished without a trace when he followed a bloodthirsty demon through a supernatural portal. 

Now he's back. 

When former police chief Bill Furman shoots the Boogeyman in a child's closet, he expects to find a body. Instead, the monster disappears and a man long believed dead steps out of the darkness with an impossible story. 

Robert has spent more than two decades trapped in a nightmare world, hunting the creature that stole his life and nearly destroyed his family. And he knows one thing for certain: The one Bill killed wasn't the only one. 

A second monster is loose in Moonrise Cove and it's out for vengeance, leaving a trail of blood, terror, and mutilated bodies in its wake. As the town spirals into panic, Bill, Robert, and Robert's son Ken must join forces with a rogue FBI agent protect the town and the people they love from an evil that can use any dark space as a doorway between worlds and turn any home into a slaughterhouse. 

But to stop the slaughter, they'll have to do more than survive the night. 

They'll have to take the fight into the monsters' world. 

And once they cross over into the Nightmare World, they may never come back
