Everyone's heard the stories about Graylock Hall. It was meant to be a place of healing - a hospital where children and teenagers with mental disorders would be cared for and perhaps even cured. But something went wrong. Several young patients died under mysterious circumstances. Eventually, the hospital was shut down, the building abandoned and left to rot deep in the woods. As the new kid in town, Neil Cady wants to see Graylock for himself. Especially since rumor has it that the building is haunted. He's got fresh batteries in his flashlight, a camera to document the adventure, and a new best friend watching his back.
