The story follows close to the episode 'Humbug'. This story is one of the best in the X-Files books in my opinion, but the only disadvantage about this book was that it is for younger children. Younger X-File fans will enjoy this book more, its easy to follow and to read. But older X-File fans like myself will find the book too easy to read. So if you are like me and you like reading a book that is going to last you at least a few days then I would give this book a miss and stick to bigger more adult X-File books. The story is 5/5 but the only shame is the quantity of the book.
