There’s no such thing as imagination… only other realities.
Dr. Benjamin Sinclair was once a rising star in neuropsychology, exploring the frontiers of consciousness. Now he's hiding in a remote cabin, haunted by nightmares and shadows that seem increasingly real. When a mysterious book appears in a bookstore that shouldn't exist, Benjamin finds written proof of his most radical theories—proof that blurs the line between science and madness.
As an ancient entity begins to stalk him across the veil of realities, Benjamin must confront the terrifying possibility that our darkest fears are not only real—but hungry. Pursued by the faceless "Watcher" and racing to decipher the truth behind the book, he must navigate a collapsing boundary between worlds to save more than just his mind… he may be humanity’s only hope.
Reality is thin. The monsters are real. And they’ve found him.
