"They say if you see him, it's already too late." Claire doesn't believe in ghosts, even though her dad is a ghost hunter on TV. But then her dad disappears. And a strange boy in her class, Lucas, knows something about ghosts. One of them has a message for her: Her dad has been taken, and he's in grave danger. Together, Claire and Lucas set out for the town of Hush Falls, where her dad was last seen. Legend says that a tall man in a dark tattered coat lurks near the local reservoir, and anyone who gets too close to old Lemuel Hush is never heard from again.
