I was unable to determine what you mean by “the dragon book”. Is that related to the recent Dragon movie that was in the Oscars? I don’t imagine you mean The Magicians book 2. Maybe you mean “Girl with the Dragon Tattoo” (terrific dragon on the cover!) but I’m honestly not really sure what you mean otherwise :(

While you could answer my above questions directly, I don’t need them answered; I’m just trying to make the point that “nicknames” cannot be easily correlated with a book when you scale up to “the entire word of readers”.
