Master storyteller Stephen King goes into the deepest well of his imagination in this #1 New York Times bestselling and spellbinding novel about a young man who inherits the keys to a parallel world where good and evil are at war, and the stakes could not be higher—for that world or ours.Charlie Reade looks like a regular high school kid, great at baseball and football, a decent student. But he carries a heavy load. His mom was killed in a horrific accident when he was seven, and grief drove his dad to drink. Charlie learned how to take care of himself—and his dad. 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. Sometimes strange sounds emerge from that shed. Charlie starts doing jobs for Mr. Bowditch and loses his heart to Radar. Then, when Bowditch dies, he leaves Charlie a cassette tape telling a story no one would believe. What Bowditch knows, and has kept secret all his long life, is that inside the shed is a portal to another world.
