Ben asked:


I heard that there is a book of Avatar the last airbender, anybody know who the author is, also anybody know where I can find that book (book 1 all of the others if possible) e.g library? In the episodes, in the introduction, it said that the previous avatar vanished, can somebody tell me what happened? Thanks
also why does he have shapes of arrows on his forehead and arms?
