Woom by Duncan Ralston

The Lonely Motel holds many dark secrets... and Room 6 just might possess the worst of them all. Angel knows all about pain. His mother died in this room. He's researched its history. Today he's come back to end it, no matter the cost, once and for all. Shyla, a plus-sized escort, thinks the stories Angel tells her can't be true. Secrets so vile, you won't want to let them inside you. But the Lonely Motel doesn't forget. It doesn't forgive. And it always claims its victim.
