Eddie Fennicks has always been a loner, content to lose himself in a mystery novel by his favorite author, Nathaniel Olmstead. That's why moving to the small town of Gatesweed becomes a dream come true when Eddie discovers that Olmstead lived there before mysteriously disappearing thirteen years ago. Even better, Eddie finds a handwritten, never-before-seen Nathaniel Olmstead book printed in code and befriends Harris, who's as much an Olmsteady as he is. But then the frightening creatures of Olmstead's books begin to show up in real life, and Eddie's dream turns into a nightmare. Eddie, Harris, and their new friend, Maggie, must break Olmstead's code, banish all gremlins and monster lake-dogs from the town of Gatesweed, and solve the mystery of the missing author, all before Eddie's mom finishes writing her own tale of terror and brings to life the scariest creature of all.
