ONCE UPON A TIME, IN THE HAUNTED CITY OF DERRY, FOUR BOYS STOOD TOGETHER AND DID A BRAVE THING. IT WAS SOMETHING THAT CHANGED THEM IN WAYS THEY COULD NEVER BEGIN TO UNDERSTAND. Twenty-five years after saving a Down's-syndrome kid from bullies, Beav, Henry, Pete, and Jonesy -- now men with separate lives and separate problems -- reunite in the woods of Maine for their annual hunting trip. But when a stranger stumbles into their camp, disoriented and mumbling something about lights in the sky, chaos erupts. Soon, the four friends are plunged into a horrifying struggle with a creature from another world where their only chance of survival is locked in their shared past -- and in the Dreamcatcher.
