"Charlie Reade looks like a regular high school kid, but he carries a heavy load. His mom was killed in a hit-and-run 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 with a locked shed in the backyard. Sometimes strange sounds emerge from it. Charlie starts doing jobs for Mr. Bowditch and loses his heart to Radar. When Bowditch dies, he leaves Charlie a cassette tape telling a story no one would believe. What Bowditch knows is that inside the shed is a portal to another world"-- Back cover.
