In this book Ryan and Sarah go on an adventure to find out what they will find at the end of their adventures. Following a sheet of paper that they must decode leading Sarah to different places where things are hidden which Sarah sends back to Ryan back in Skeleton Creek. In the end they become the new Crossbones and find Edgar Allen Poe's ghostbook where he admits he is part of the Crossbones and includes many ideas about stories he's had. I loved this book and if you get scared easily, leave the the lights on because this book gives you passwords to watch videos online explaining some things in the book.
