More to be added.


  • During her Kingdom of Ash tour, Sarah confirmed that the book will be an encyclopedia of the series written ten years after the last book, giving us glimpses of where the characters are at that point.[4]
  • Sarah also mentioned that The World of Throne of Glass will be chronicled by "a cranky, old librarian" who interviews different characters after the war in Kingdom of Ash. There will be illustrations, interview snippets, etc.
