What’s even on this blog?
My translations
Chapter 1 of the new Inkworld book, Color of Revenge (you can click through from there, I translated all 14 available chapters) (EDIT: Cornelia confirmed that she will need to rewrite large parts of the story - by the time these chapters were released almost three years ago it was already clear they would change significantly. While basic story elements will probably stay the same, we don’t know how much will make it into the final book.)
The Silver Book, a bonus chapter originally published in the Inkheart Anniversary Edition™ in 2013 to explain the origins of the silver-tongue ability (confirmed canon by Cornelia in this livestream)
