Charlie Reade looks like a regular high school kid, great at baseball and football, a decent student. But when Charlie is seventeen, he meets a dog named Radar and her aging master, Howard Bowditch, a recluse in a big house at the top of a big hill, with a locked shed in the backyard. When Bowditch dies, he leaves Charlie a cassette tape telling a story no one would believe - inside the shed is a portal to another world. Legendary storyteller Stephen King goes into the deepest well of his imagination in this spellbinding novel about a seventeen-year-old boy who inherits the keys to a parallel world where good and evil are at war, and the stakes could not be higher - for their world or ours.
