Because it is supposedly a draft copy of the game, the book is covered in annotations by Harry Dresden, Bob the talking skull, and Billy Borden and these take the form of highlights, notes in the margin, and post-it notes attached to the pages both as explanations of the rules and as snark between the characters. It is also split into two separate books; "Your Story" containing the rules and setting notes, and "Our World" containing a list of the movers and shakers in the "Dresden Files" universe as well as statistics for most supernatural creature types in the "Dresden Files" universe along the lines of a monster manual in "Dungeons & Dragons".
