David has two problems. Tucker—the violent alternate personality he's spent years trying to kill. And the fact that Tucker might be the only thing keeping him alive. When his psychiatrist takes a post at the remote Shepard Institute, David follows—uninvited, under a false identity, with nothing to lose. What he finds is a locked ward full of broken people, an old man who seems to know exactly why he's there, and something ancient moving through the building like a current. It was here long before any of them. And it's been waiting for exactly the right person to carry it forward. GOAD doesn't want your soul. It wants something worse. A supernatural thriller set in 1996. For readers of Stephen King and Dean Koontz.
