The Nightmare Man by J.H. Markert

After suffering weeks of writer's block, bestselling author Ben Bookman visits his family estate, Blackwood mansion, to the forbidden room filled with thousands of numbered books. Books without words. He doesn't remember anything that happened that weekend, only that he finished his book, The Scarecrow. But when the events in his horror novel begin to happen in real life, Ben starts to look into the history of the mansion and that forbidden room and to realize he may have released a nightmare too terrifying to contain.
This story that brings nightmares to life is chilling and I loved every minute of it. It has a unique plot that kept me guessing until the satisfyingly grim ending. The truth behind the books in the Atrium was soo great!
