I just got news that confirms that dragons from Pantala and Pyrriah will meet in book 12.

       I also have a theory about a part of the cover:

      I think that this will be included in the cover of book 12. This isn't confirmed; it's just a picture I found. Still, this looks like Joy Ang's art, so I figured "hey look, this picture of Cricket must be in the cover of 12".

P.S.
       I absolutely love Cricket. She's awesome!
